No bad blood, but still a few tears. When Nina Dobrev and ex Ian Somerhalder reunited at The CW's Upfront even in New York City on Thursday, May 16, the weight of their breakup still made the Vampire Diaries actress a bit misty-eyed.

"Her eyes welled up. She looked so sad," a source tells Us Weekly of witnessing Dobrev, 24, having a heart-to-heart with Somerhalder, 34, at the end of the night. Earlier this month, Us Weekly broke news that the pair, who costar on the CW show, split after three years of dating.

"They avoided eye contact," the source added of the pair's interaction before their chat. "It was awkward."

For more details about the couple's split and uncomfortable reunion, watch this week's Hot Stuff video, as explained by Us Weekly senior editor Ian Drew and special guest Zendaya -- the Dancing With the Stars finalist and Disney starlet is set to release her new single, "Replay," this July.
