Proud new mama Tracy Anderson can't help but show off her adorable two-week-old baby girl, Penelope.
Penelope -- who was born May 21 -- is the celebrity trainer's first child with husband Matt Mogol, whom she wed in a Big Sur, Calif. ceremony on September 27 of last year.
Their new bundle of joy joins a half-brother, Sam, Anderson's 13-year-old with her first husband (former NBA star Eric Anderson).
The fitness guru and founder of the Tracy Anderson Method is currently hard at work adapting her techniques for expectant moms with The Pregnancy Project, due out later this summer.
"It has always been a dream of mine to give women effective tools throughout their pregnancies and the Pregnancy Project wouldn't have been possible without my daughter Penny," Anderson tells Us Weekly about her new endeavor.
In March, some of Anderson's famous pals celebrated the second-time mom at a workout-themed baby shower.
Among the attendees? Catt Sadler, Sally Pressman and Nicole Richie. Anderson's celeb friends who couldn't make it -- including Gwyneth Paltrow, Jennifer Lopez and Courteney Cox -- each sent along generous gifts from her baby registry.
"The cake and tablecloths were all pink and green," a source told Us about the fete. "Each table had Barbie dolls that were custom-made to look like workout Barbies carrying weights." Plus, "They had Miss Piggys -- little toys where you push on the toy and you hear the [Olivia Newton John] song, 'Let's Get Physical.'"
Adds the source, "Everything was very girly!"
