Jaimee Foxworth

Jaimee Foxworth, a former child star on and recent patient on Celebrity Rehab with Dr. Drew, is five months pregnant by her longtime boyfriend, according to People.

"I haven't been this happy in years," said the 29-year-old. "I am excited about what the future holds for us."

Foxworth plans on releasing an autobiography in mid-2009 documenting her troubled life. The actress, who was quietly written off as the youngest daughter on Family Matters, lost all her income from the show and turned to adult films and marijuana abuse.

"Being sober has opened my eyes to a whole new world," said Foxworth. "I've been through a lot of pain in the past and I never really wanted a child until recently. I now look forward to years of joy to share with my child."
