Glee's February 14 episode, titled "Heart, "sounds like a true valentine to fans — with Mercedes singing a Whitney Houston classic, Kurt receiving a surprise visit and The Glee Project winner Samuel Larsen finally making his debut.

"It's Valentine's Day and everyone's really excited about it," says Matthew Morrison (Will Schuester).

"There is a lot of love in the air during our Valentine's Day episode," echoes Naya Rivera (Santana). "There's a big dance at the school and Brittany [Heather Morris] and I are definitely going to go together. So maybe fans will get what they've been wanting."

What fans have been wanting, according to the obsessive tweets I've been receiving, is some serious Brittana smooching. Well, get ready guys. Heather confirms, "They'll be a lot of kissing for me and Santana. Naya and I had to do it over and over and over again."

Heather also offers a Valentine's Day Easter egg clue for fans. "Here's something to look for," she says. "Somebody from our set dressers stamped a candy heart with 'Teen Lesbians.' It's really funny and I hope somebody spots it." 

Fans also won't be able to miss Larsen's long-awaited debut in the jam-packed hour as a character named Joe Hart.

Among the other developments:

"Will and Emma [Jayma Mays] get in a fight," reveals Matthew, who doesn't see a wedding in Will and Emma's immediate future. "I don't think there will be a ceremony just because a lot of attention needs to be paid to the kids who are exiting the show."    

Chris Colfer (Kurt) confirms that while Darren Criss (Blaine), who was in New York City performing on stage during the shoot, "is in the episode, it's not in the way you might think. But there's definitely a huge development for Kurt in that episode that involves someone in a gorilla costume." Hmmm...

Though Chord Overstreet's Sam never got to sing Nat King Cole's "Nature Boy," as was planned as a mash-up with "Human Nature" in the Michael Jackson episode, the late great musical legend's romantic ballad, "L-O-V-E" will be performed by lovebirds Mike (Harry Shum Jr.) and Tina (Jenna Ushkowitz). 

And what of Sam and Mercedes (Amber Riley)? "There's a lot of love and a little bit of heartbreak in the episode," Chord tells me. "Mercedes still has her boyfriend, and I'm still trying to jump in on that and convince her to break up with him. There's a lot of that throughout this episode. He acts sweet and sings to her to win her over." 

Look for Mercedes, Sam and Joe Hart to sing Gym Class Heroes' "Stereo Hearts," while Mercedes will solo on "I Will Always Love You," made famous by Dolly Parton and Whitney Houston. 

Ah, sweet amour... this one sounds like one not to be missed!
