Okay, not really. Turns out they just bumped into each other the other night!

Buff-for-life Mario Lopez and his preggers girlfriend Courtney Mazza stepped out in Hollywood over the weekend and, by chance, ran into Wladimir Klitschko, the Ukrainian heavyweight boxer - who's also dating Hayden Panettiere!

The hot bodied buds shook hands and posed for some pix. Bromance alert!
