Exclusive! This Is What Rehearsals For Grease: Live! Look Like For Carlos PenaVega

Kenickie is ready for that "Greased Lightnin'." Carlos PenaVega is making sure of that. The actor (whose parents have Spanish, Venezuelan, and Dominican roots) has been hard at work — straight from a stint competing against wife Alexa Vega (of Spy Kids) on Dancing With the Stars — and getting ready to step into the role made famous by Jeff Conaway on the set of Grease: Live!

But the star is taking a few minutes from his busy schedule as one of Rydell High School's resident bad boys to give us a peek at what a typical day of rehearsals for the live show looks like. From an early wake-up call to spending time with the T-Birds and Pink Ladies, including Vanessa Hudgens and Julianne Hough, keep scrolling to see Carlos's exclusive photo diary, and then check out the entire cast of the show — and tune into Fox on Jan. 31 at 7 p.m. EST to see them perform.
