Jessica Simpson is already taking tips from her famous pal Jessica Alba when it comes to bouncing back from having a baby.

Although Simpson is still pregnant, she gushed over Albas post-baby body on Twitter on Tuesday.

Four months after giving birth to her second daughter, Haven, Alba debuted her svelte figure in a series of pictures in a hot pink bikini while on vacation at the beach with her family.

That same day, Simpson tweeted, "New goal: look like @jessicaalba after baby. Job well done lady!" To which Alba tweeted back OMG! Ur so sweet! Thx hon!"

When it comes to parenting advice, Alba said she will be talking to her friend behind closed doors. I'm friends with her so I'm going to talk to her about that personally," she told People.

E! Online reports that the twosome have more in common than motherhood. Albas husband, Cash Warren, and Simpsons fianc Eric Johnson both attended Yale and graduated together. Over the summer, both ladies attended the 10-year reunion with their significant others.

Alba has two daughters, Honor and Haven, with Warren, while Simpson announced she was expecting her first child with Johnson in October.
