Tristan and Tahyna (FOX News)
Tristan MacManus, Irish hottie and star on ABC’s ‘Dancing with the Stars,’ is reportedly off the market despite his charmingly modest ways. MacManus is rumored to be dating actress Tahyna Tozzi for a few months now.

A source tells FOX411’s Pop Tarts that MacManus has been seeing Tozzi (24), a native of Australia, for a couple of months after meeting through a mutual friend.

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

MacManus is, of course, busy with his demanding schedule for ABC’s hit show ‘Dancing with the Stars.’ In his second season on the show, MacManus is partnered with singer Gladys Knight. The two are safe for another week after tying for last place on Monday’s competition show.

Tozzi made an appearance in 2009’s ‘X-Men Origins: Wolverine,’ and more recently, in the television series reboot of ‘Charlie’s Angels.’
