Katharine McPhee & David Foster's Son, 2, Is 'Coming For' Travis Barker In Impressive Drumming Video

Katharine McPhee and David Foster's baby boy didn't fall far from the tree when it comes to his musical skills! The 39-year-old "American Idol" alum took to her Instagram on Oct. 15 to share a video of their 2-year-old son Rennie crushing it on a mini drum set. Katharine even gave one of pop music's most famous drummers a funny shoutout, captioning her adorable post, "coming for ya @travisbarker." The proud mom isn't the only one who noticed her son is an up-and-coming rockstar. Jenna Dewan took to the comment section to show how impressed she was, penning: "Wait this is insane!" And Amanda Kloots wrote: "Insane talent." This isn't the first time Katharine and her husband have posted about Rennie's drumming skills. David took to his Instagram back in January to give fans a peek at his only son's musical talents. Rennie is Katharine's first child and the 73-year-old musician's sixth, as he has five adult daughters.
