The 30-year-old actress opened up about their romance in December, saying the third time around is going "great."

"It’s going so great," Duff said on "The Talk." "I mean, this is the third time that we’ve dated."

She added, "Timing is such a big deal… third time’s the charm...I think that you have history and a past with someone and love, and just because it doesn’t work out the first time, the second time… as long as there’s not too much damage done, then, it can always work out again."

Duff has a son, Luca, 6, with ex-husband Mike Comrie.
