John Travolta's 5-month-old baby Benjamin showed off his playful tricks while out shopping with dad in LA yesterday. The father-son duo enjoyed their quality time together and the little guy clearly knows how to put a smile on dad's face. John's wife Kelly Preston brought Ben out in NYC last week for one of his first public sightings since his People magazine debut. John is also gearing up to return to making movies, since taking a break after 2010's To Paris, With Love. He'll be playing John Gotti Sr. in the upcoming Gotti: Three Generations, which, after much drama, officially also stars Lindsay Lohan as Kim Gotti. The troubled starlet spoke about costarring with John Travolta in the Gotti film, saying "I think it's a great story to be told. I'm honored to be working with John Travolta and Joe Pesci. . . . You don't get to see the heart behind the story and the real side of people. I can relate to that because I think that I've been portrayed in a certain light. I just want to do my best to show what their family really went through." Shooting starts on location in New York soon, so the Travolta family will be setting up shop on the East Coast for John to take on the iconic mob family patriarch.
