Hilaria Baldwin is still working out Amy Schumer‘s latest gag.

The 36-year-old wife of Alec Baldwin took to Instagram on Sunday to share a photo of herself wearing only underwear while cuddling up to her newborn, Eduardo.

In the pic, Baldwin’s toned figure was on full display, which earned her praise in the comments, considering she gave birth three months ago.

Schumer, 39, seemed to have noticed the stunning pic and thought she’d jump on the opportunity to poke fun at herself, as she often does in regard to her figure and body type.

The “Trainwreck” star snagged the images and posted it on her own Instagram later that day. She joked in the caption as if she were Baldwin while pretending the baby was her own 1-year-old son Gene.

“Gene and I wanted to wish everyone a happy holiday season,” she said in the caption. “Enjoy it with whatever family members are talking to you this year.”

“I literally had to have someone explain this joke to me,” she said. “Still don’t get it 100%…But…”
