Looks like some of the fitness world’s biggest celebs will be spending more time warming up milk bottles than choreographing workout classes in the coming months.

This week, People revealed that celebrity trainer Jillian Michaels recently became a mom—of two. Michaels’ partner Heidi Rhoades gave birth to a baby boy, Phoenix, on May 3, and the couple brought home an adopted two-year-old daughter from Haiti, Lukensia, the same week.

Then, on Monday, Tracy Anderson gave birth to her second child, a baby girl she named Penelope, with her husband, Matt Mogul.

Cue the speculation about how long it will take Anderson to lose the baby weight (sigh) and how long it’ll be before Michaels’ kids are photographed in tracksuits.
