Hmm ... the last time Ashton Kutcher, 33, partied with Danny Masterson he allegedly cheated on his wife, Demi Moore, 48.

Hopefully that didn't happen again Tuesday night, when Ashton and his That 70s Show pals, Danny Masterson and Wilmer Valderrama, reunited in LA.

The trio met up for a party at Warby Parker Eyewear's boutique in LA. Masterson was DJ-ing the event under his spinner name, DJ Mom Jeans.

"Epic nite gents," Masterson Tweeted. All three posted photos of their reunion -- Ashton's are posted here.

Kutcher also didn't help his situation with Demi on Tuesday night's episode of Two and a Half Men. His character, Walden Schmidt, said when looking at a new apartment, "Can I have a jacuzzi on the balcony? Because I'm single now, so I'm going to be having sex with a lot of women I haven't met yet."

Sara Leal, 22, Ashton's alleged one-night stand, revealed that the two hooked up in the hot tub on the balcony of his suite at the Hard Rock Hotel in San Diego on Sept. 24.
