ET Now: 'Transformers 4' Set, Spotlight on Bruno Mars' Sisters

By
In today's ET Now we are taking you to the set of Transformers: Age of Extinction, where our own Rocsi Diaz was up-close and personal to the action and caught up with the film's star, Mark Wahlberg and director Michael Bay.
Bay transformed Detroit into Hong Kong for the film, and as Rocsi found out, the set was nothing short of explosive!
Transformers: Age of Extinction hits theaters June 27th.
Jaime, Tiara, Tahiti and Presley-- sisters of Grammy Award-winning singer/songwriter Bruno Mars-- are making a name for themselves as they pursue their own music careers.
Between their music and WE TV reality show, the group known as the The Lylas are hoping to step out of their brother's shadow and launch their own music careers.
"A lot of people just assume that because we're his sisters we're just riding his coattails and we're getting things handed to us, but it's not that way, and you'll see that on the show," Jaime explains.
The Lylas airs Friday nights on WE TV.
