Ed Westwick & Jessica Szohr
Who and what now? Gossip Girl co-stars, Chuck and Vanessa.
And they're back on? Spotted. Chuck Bass and Vanessa enjoying a cosy lunch together at Allswell restaurant in Brooklyn on February 11, with onlookers saying they were "kissing and making out". Wonder what Blair will have to say? XOXO.
Back up a bit, why'd they split in the first place? The pair broke up in April last year, amid rumours Jessica had cheated on the Brit star with his pal, New York rich kid, Marco Minuto.
Any interim hook-ups? Not for Ed, who was "heartbroken" over the split. Bless.
Dianna Agron & Sebastian Stan
Who and what now? You know, Glee's gorgeous Quinn Fabray and Gossip Girl's Carter Baizen.
And they're back on? Yep, the loved-up pair chose Valentine's Day to publicly debut their re-love, with dinner at Hollywood's La Poubelle Bistro, followed by some snogging whilst they waited for their car.
Back up a bit, why'd they split in the first place? They split in December after several months together, with a source spilling, "She was always worried that Sebastian would cheat on her while he was off filming, even though he never would."
Any interim hook-ups? Dianna ‘enjoyed' a very public fling then split with Brit bad boy, Alex Pettyfer.
Michael C Hall & Jennifer Carpenter
Who and what now? Dexter's brother and sister, Dexter and Debra.
And they're back on? Quite an unexpected one this, but the pair who eloped on New Year's Eve in 2008, saw their divorce finalised in December 2011. But last week, they were spotted out and about in LA being all hand-holdy and stuff.
Back up a bit, why'd they split in the first place? Ooh, let's just activate our ‘allegedly' button… okay, here goes. Dirty little rumours from the set of Dexter pointed to an alleged fling between Michael and their co-star, Julia Stiles.
Any interim hook-ups? *Cough* Julia (allegedly) *cough*.
