Steve Martin brands Ben Stiller a "nepo baby" in a tongue-in-cheek new advert.
The comedy veteran trades insults with the 'Zoolander' star in a commercial for Pepsi Zero Sugar which is due to air during the Super Bowl later this month with Steve making a dig at Ben for embarking on a career in Hollywood after growing up with famous parents Jerry Stiller and Anne Meara.
As the pair promote the fizzy drink, they talk about acting with Ben starting off: "As actors, in a way, we never really stop acting" before Steve cuts him down by saying: "For example, Ben is acting right now like he's not intimidated by standing next to me."
Ben then shoots back: "And Steve‘s acting like he’s not lucky to be here," prompting him to reply: "Oh, and Ben‘s acting like that whole awkward thing he does is a character and not his actual personality."
The 'Tropic Thunder' star snips at Steve by calling him a "banjo player" in reference to his longtime devotion to the instrument and the 'Naked Gun' star hits back by branding Ben a "nepo baby".
The advert ends with the pair agreeing their are both fans of each other's work, with Ben asking Steve if he really meant it with the actor joking: "I was acting."
The commercial is among a slew of celebrity-packed adverts which will all grace the airwaves during the Philadelphia Eagles' clash with the Kansas City Chiefs on February 12.
