Do those full lips and shaggy hair give you a Jumpin' Jack Flashback? Mick Jagger's 14-year-old son, Lucas, attended the premiere of Get on Up in New York on Monday night with his mother, Brazilian model Luciana Gimenez. Looking like Mick’s mini-me, Lucas came to support his legendary rock star dad who produced the James Brown biopic. (The Rolling Stones frontman also makes an onscreen appearance of sorts — he's portrayed in the movie by costar Nick Eversman.) Jagger himself was all smiles on the red carpet, though he told the 'Today' show just days ago that it has been a "very hard year" following the death of his girlfriend, fashion designer L'Wren Scott, in March. Meanwhile, star Chadwick Boseman, who plays the Godfather of Soul and walked the carpet along with his castmates, said that he needed some convincing to take on the role, but eventually came around. "I knew that everybody that was involved was going to be at the top of their game, so why not try?” he told The Hollywood Reporter.
