The former couple was spotted sharing the same table at Tao nightclub on Friday night as the hot spot celebrated its 1000th night.
So did the exes look romantic?
Not exactly, but they looked comfortable and friendly, according to a source.
"They seemed at ease hanging out and taking in the crazy scene," my source says.
That scene included the night's host Jay-Z being presented with a 15-liter bottle of Ace of Spades champagne—that cost $100,000!
Jay, sans pregnant wife Beyoncé, performed at the music festival held at the MGM Grand Arena on Friday night, where Joe was a presenter. Ashley was spotted backstage as well, but declined interviews.
Joe's rep didn't return our request for comment. Whether they're rekindling their romance or not, it's nice to see two mature exes getting along and having a good time together.
