Jessica Simpson encountered her ex Tony Romo -- and his current girlfriend, Candice Crawford -- at Saturday's Bloomberg/Vanity Fair afterparty for the White House Association dinner.
During the fete, held at the French Ambassador's residence in Washington, D.C., Simpson, Romo and Crawford chatted for about five minutes on the balcony.
A witness tells UsMagazine.com that the trio's chat was "tense."
Adds another observer: "You could tell they were uncomfortable."
"It wasn't awkward," another source counters. "Candice didn't say much. Jessica and Tony are still friends and talk. It was the first time Jessica met Candice."
After over a year-and-a-half of dating, Dallas Cowboys player Romo, 30, dumped Simpson last July on the eve of her 29th birthday. He and Simpson-lookalike Crawford -- Chace Crawford's 23-year-old little sis -- began dating last fall.
But Simpson may have a new love in her life. Earlier in the evening, the Price of Beauty star told Us, "I have some [romantic] situations that I am feeling out."
Indeed: the new Us Weekly reports of Simpson's on-the-downlow romance with The Hurt Locker's Jeremy Renner. Find out about their top-secret tryst in D.C. in the new issue, on newsstands today!
