Amanda Bynes

On Tuesday, Amanda Bynes will be in court to face charges in her bong-throwing arrest from May. It's a far cry from where the former Nickelodeon star was just six years ago, when her career seemed full of promise after charming turns in She's the Man, Hairspray and Sydney White.

But in recent years — or more specifically, in the past 12 months — the 27-year-old's behavior has gone from odd to bizarre to downright alarming at times between her legal woes, strange appearances and crazy tweets. Here's a timeline:

The biggest celeb feuds

May 1, 2013: Bynes tweets topless photos of herself and gets into a brief Twitter feud with Jenny McCarthy after she mistakenly tweets that police are at Bynes' apartment. (Publicist Jonathan Jaxson had tweeted that he had called police to check on the actress because "she is soooo messed up on drugs," but it later turned out that police never went over.) Bynes lashes out at McCarthy, calling her "ugly" and saying that she looks "80 compared to me." After McCarthy apologizes, Bynes tweets, "thanks! I'm sorry I offended you! You're beautiful! I was lying! I'll delete our tweets!"

May 9, 2013: Bynes pleads no contest to driving with a suspended license and is sentenced to three years of probation and ordered to pay a fine of $300.

May 23, 2013: Nearly a week after she gets rejected from a flight for trying to use Google as a form of identification, Bynes is arrested after police said she threw a bong out of her Manhattan apartment window. According to police, a building official called the cops after spotting the star in the lobby talking to herself and with a joint. When law enforcement arrived at her apartment and spotted a bong, Bynes threw the water pipe out the window, police said. Bynes, who faces charges of unlawful possession of marijuana, reckless endangerment and tampering with evidence, is released on her own recognizance after appearing in court the following morning in a platinum blonde wig.

May 25, 2013: Bynes accuses her arresting officer of sexual harassment, claiming that he "slapped my vagina," and says she plans to sue the NYPD and become a rapper. After conducting an investigation, police say there was no evidence of sexual harassment, after which Bynes tweets that her lawyer is getting her case dropped.

May 26, 2013: Unprovoked, Bynes goes after Rihanna on Twitter, writing: "Chris Brown beat you because you're not pretty enough. No one wants to be your lover so you call everyone and their mother that I almost named my new dog Rihanna." Rihanna fires back: "Ya see what happens when they cancel intervention?" Bynes later deletes her tweets and sends out a nicer message to the singer: "This is a mocked up image I found on the Internet that I LOVE! I love @rihanna! She's such a beauty!"

June 19, 2013: After flip-flopping on Drake's looks, Bynes, in a series of tweets, says that she was born with a birth defect — webbing in between her eyes — with which she as "suffered" for 27 years, will be having plastic surgery on her nose, and sings the praises of going under the knife. "There's a surgery for everything that's wrong with you!" she writes. Three days later, she says she's had the surgery.

July 8, 2013: Bynes tweets that Obama and Michelle Obama are ugly.

July 9, 2013: Bynes arrives for her court date wearing black sweatpants, sunglasses and a sleek blue wig, looking much more put together than at her arraignment. Bynes' hearing is postponed until Sept. 26. Though Bynes remained silent in court, on Twitter the actress shares plans for more surgeries. Bynes claims her nose is broken, hindering her ability to breathe and making it so the bone under her eyes protrudes.

July 22, 2013: Bynes was hospitalized on a 5150 involuntary psychiatric hold after she started a small fire in someone's driveway in Thousand Oaks, Calif. The night before, Bynes was involved in an altercation with a cab driver after she was denied entry into a retirement community, which called her a cab. She was kicked out of the cab after saying that she didn't have money and police were subsequently called. The three-day hold was extended to two weeks to allow doctors to properly diagnose her. Meanwhile, her parents filed for temporary conservatorship of Bynes, the ruling for which was delayed until Aug. 9.

Aug. 9, 2013: Bynes' doctors extend her psychiatric hold for another 30 days. A judge can only grant such an order if the patient is "gravely disabled as a result of a mental disorder."Bynes' mother Lynn is also granted conservatorship, givng her the power to decide where Bynes lives and control of her $3 million fortune.

Sept. 30, 2013 Upon doctors' recommendation, Bynes was transferred from UCLA Medical Center to receive "specialized treatment in a private facility outside of Los Angeles."

December 2013-June 2014 Bynes' fortunes appeared to be on the upswing. After being released from treatment to live with her parents, she started to get her life in order. She pleaded no contest in her initial DUI case stemming from 2012, and although she was put on three years of probation, she avoided jail time. In the spring she resurfaced on Twitter with a very innocuous tweet that announced she was studying at FIDM, the Fashion Institute for Design & Merchandising. Finally, that summer, her bong-throwing case was thrown out because Bynes had obeyed judge's orders to attend counseling twice a week and stay out of legal trouble.

Sept. 28, 2014 Bynes went back to her erratic behavior when she stopped her car in the middle of a Los Angeles intersection, and the California Highway Patrol determined that she was driving under the influence of a drug and booked her for her second DUI.

Oct. 10, 2014 After a series of bizarre tweets during which she accused her father of sexual molestation and then later recanted and blamed the posts on a microchip implanted in her brain, Bynes was placed in an involuntary psychiatric hold by her parents and taken to a Pasadena hospital where she will be held a minimum of 72 hours.

Oct. 30, 2014 Bynes was released from the hospital days after a judge extended her psychiatric hold to a month. Hours later, she was reportedly seen talking to herself and took to Twitter the next day to blast her family, including resurrecting the claims against her father, whom she called a sexual predator. Bynes was due in court on Oct. 31 to regain control of her finances from her mother, who had been granted conservatorship again.
