EXCLUSIVE: Beau Casper Smart on Ex Jennifer Lopez's New Relationship with Alex Rodriguez: 'Nothing But Love'

The 'Dirty Dancing' actor says he wants 'nothing but the best' for his former flame.

Jennifer Lopez's former flame, Beau Casper Smart, has nothing but support for his ex-girlfriend's burgeoning relationship with baseball legend Alex Rodriguez.

The actor and choreographer helped launch Lay's new Poppables snack chips by choreographing a special dance session in New York City on Thursday, and stopped to talk with ET about his "good" post-breakup relationship with the "On the Floor" singer.

"[We're] friends," Smart said, adding that the exes have "nothing but respect and love for each other."

The 29-year-old performer said he was "of course" happy for Lopez's new relationship, explaining, "I want nothing but the best and love [for her]."

Lopez and Smart, who first sparked romance rumors in 2011, called it quits in 2014. They rekindled their relationship in 2015, before splitting once again in August 2016, and have publicly remained amicable since parting ways.

Before calling things off, Smart went on tour with Lopez as a choreographer and dancer. Reflecting on that experience, Smart shared, "It was tiring but nice to travel around the world in six months, especially with someone you're with and you get to enjoy it together."

"The work was a lot and we constantly were fixing and changing and shifting and making the show better, daily. But it was fun," he added.

Smart is now focusing on his acting career, and said he's excited to be a part of ABC's upcoming musical reimagining of Dirty Dancing, co-starring alongside Abigail Breslin, Colt Prattes, Sarah Hyland, Debra Messing and Katey Sagal.

"I'm proud to be a part of something so iconic and legendary," Smart marveled. "I just feel blessed to be a part of it… and have such a good time. All the cast and actors, we got super close. We still keep in contact daily."

The original Dirty Dancing turns 30 this year -- a milestone anniversary Smart shares with iconic romantic drama -- and Smart has a few fun ideas for how he might spend his big day on April 6. While he usually "could care less" about birthdays, he admitted the big 3-0 has made him "a little itchy," and he wants to make sure to celebrate the occasion in a big way.

"I might rent out a big restaurant and do a big party thing," Smart said. "Maybe paintball with the guys."

Smart's made-for-TV reimagining of Dirty Dancing airs May 24 at 8 p.m. ET/PT, 7 p.m. CT on ABC. Check out the video below for a look at the upcoming musical extravaganza.
