Diane, 42, posted a photo of her at the gym. She wore a red bra and checkered pants that clearly displayed her glistening abs.
"Am I showing off ? F**k yeah," she wrote. "Because it’s been hard work to get my abs back. I didn’t think it was possible after having a baby. And certainly not at my age."
Diane welcomed her first child with Norman, 50, in November of 2018.
This is The Walking Dead star's second time being a father. He has a 19-year-old son named Mingus who he shares with ex-girlfriend Helena Christensen.
The Troy star has been spotted breaking a sweat at the gym several times since giving birth.
