Lance Bass and Andy Cohen might be the friendliest ex-hookups ever.

The ‘NSYNC pop star took to Twitter to wish the Bravo host a happy birthday weeks after Cohen chatted about some steamy history with the singer.

“Happy Birthday to the one that got away @Andy!!!!” Bass, 36, Tweeted on Tuesday, topping it off with smiley emojis and lots of hearts.

And Cohen, who turned 47 on Monday, took his pal’s Tweet in jest, responding with a sweet, “Awwwwwww. My man. XOXOXOXO.”

Cohen revealed the pair’s past to Real Housewives of New York personality Sonja Morgan, 51, during an episode of Watch What Happens Live on May 5.

In the episode, the reality star asked Cohen to name his most famous hookup.

Cohen noted shortly after on Twitter that the fling was already years in the past – and that Bass is a married man now! (And Bass’ husband, Michael Turchin, was a great sport.)
