Pink  sweatshirt motorcycle sagebrush cantina

Mommyhood is doing wonders for Pink!

Leaving her baby girl Willow Sage at home, the "Raise Your Glass" singer grabbed her hubby Carey Hart so the two could ride their motorcycles from Malibu to Calabasas for a fun lunch with pals.

Pink - casually dressed in a pink zip-up hoodie, leather jacket, oversized black sweatpants, black Converse Chuck Taylors, and aviator sunglasses - was literally glowing as she exited the Sagebrush Cantina. Her smile is so big, we can't help but smile too!

But really, can you blame the gal for that grin? She's madly in love with her new baby - and her hubby! See what she Tweeted about Carey ... after the jump.
