Mark Ballas has a lot on his plate right now -- but he's not complaining!

ET caught up with the former Dancing With the Stars pro on Friday at the Lunt Fontanne Theater in New York -- where he gushed about starting his run as Frankie Valli in Broadway's Jersey Boys and planning his wedding to fiancée BC Jean.

"We're enjoying it," Ballas said of his busier-than-usual last few months. "My fiancée just went back to LA. She's been out here for the opening night [on Oct. 18] and saw my matinee the next day."

The couple, who were based in Los Angeles before Ballas' big Broadway role, have found Facetime to be a huge asset in wedding planning from opposite coasts.

"She's been looking at tablecloths, settings and plates and dishes and the cutlery and what cocktails we're having. She's been Facetiming me in all of it. It's amazing," he said. "It's coming up really quick, so it's great. I try not to get overwhelmed. I just take each day as it comes and I'm blessed and honored right now."

"Getting to star on Broadway has been a dream of mine for years," Ballas continued. "I went to musical theater school for nine years… so I'm finally putting it to good use."

Putting his musical theater experience "to good use" might be an understatement -- the Houston, Texas native snagged the role of Frankie Valli before the hit musical leaves Broadway on Jan. 15, and was picked for the part by Valli himself.

"To be the last guy, I’m just very blessed and humbled and grateful," he said.  "To be honest, for the first 30 seconds [of meeting Valli] I was like [starstruck] and I don't really get like that. That was incredible. He's an icon."

While Ballas and Jean juggle wedding planning with Broadway, Ballas' longtime pal and best man Derek Hough is picking up some of the slack, and taking care of the Bachelor party.

"Derek throws a good party," he dished. "Man, I don't know [what he has planned]. When you see him, you ask him."
