New Couple Alert: 'DWTS' star Tristan MacManus dating actress Tahyna Tozzi

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.
