Meghan Trainor is pulling back the curtain on when she feels sexiest as a mom of three with husband Daryl Sabara. "There's not a lot of time for sexiness when you have [kids that are] 5, 2 and a newborn," Trainor, 32, exclusively shared in Us Weekly's latest cover story. "And I think anyone with a kid under 5 knows what I'm talking about in marriage. So it is rare." Trainor's latest album, Toy With Me (out April 24), features a track called "Pink Cadillac," which is an interpretation of Bruce Springsteen's 1984 song of the same name but is very sexy and cheeky.
