He’s the “it” boy on ABC’s “Dancing With the Stars,” having partnered with Nancy Grace last season, and this season taking Gladys Knight for a rumba and samba.

But sorry ladies – Tristan MacManus is taken.

Sources tell FOX411’s Pop Tarts column that the Irish native has been dating Australian actress Tahyna Tozzi, 24, for a couple of months now, having met through a mutual friend.

“They’re both busy with their careers, but it just works," said the insider. "They couldn’t be happier.” 

In 2009, Tozzi appeared in “X-Men Origins: Wolverine” as Emma, a captured mutant able to turn her skin into diamond, and most recently filmed “Trophy Kids” alongside “90210” star Ryan Eggold.
