Stacy Keibler is already breaking out the pink!

The Supermarket Superstar host, 34, showed off her growing baby bump while working up a sweat earlier today. Keibler wore a tight bright pink tank top with black leggings as she held on to a water bottle and zones out to whatever is playing through her earphones.

"Can't wait to spend next #MothersDay with this little angel in my arms #happymama #babybump," she wrote with a precious photo of herself holding her bare baby bump over the weekend.

E! News confirmed in April that the celeb is expecting a daughter with husband Jared Pobre.

"They're beyond excited and happy," a source says.

The couple announced Keibler was pregnant with their first child in late March. This came just a couple of weeks after the former Dancing With the Stars hoofer married the tech entrepreneur in a surprise sunset ceremony on a beach in Mexico.

"My happiness is indescribable!" Keibler told People magazine at the time. "Marriage is the ultimate bond of love and friendship. It means putting all your faith and trust into a person that you can't help but believe is your soul mate. Someone who has all of your best interests at heart; someone handpicked for you, to help you grow and be the best person that you can be. Jared is all of this for me."
