Pumping iron with pop! Jennifer Hudson's 5-year-old son David Jr. is ready to follow in his WWE wrestler dad's footsteps — and he's already been bitten by the work out bug!

The super-cute tot was photographed lifting weights with his namesake dad David Otunga during an evening work out session at the home the wrestler shares with his long time love, Hudson.

"Late night training session with my workout partner, Mini Me," 35-year-old Otunga captioned the adorable picture. "I want to work out with you every day Dada." #Flattered," the proud dad wrote.

American Idol season 3 alum Hudson talked about life as the fiancee of a WWE wrestler during a recent appearance on James Corden's Late Late Show.

"Sometimes he likes to experiment on me and put me in a head lock," the star, 36, joked.
