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 [1] Alexa Vega (of Spy Kids) on Dancing With the Stars [2] — 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 [3] and Julianne Hough, keep scrolling to see Carlos's exclusive photo diary, and then check out the entire cast of the show [4] — and tune into Fox on Jan. 31 at 7 p.m. EST to see them perform.
