Getting some fresh spring air, Gwen Stefani took her baby boy Zuma to the Indian Wells Tennis Tournament yesterday afternoon (March 18).

The “Hella Good” songstress and her little guy enjoyed some socializing with tennis great Roger Federer’s girlfriend Mirka Vavrinec, who herself is pregnant with the couple’s first child.

And it looks like Miss Vavrinec is already embracing her maternal instinct, as she got

along famously with Zuma, tickling and giggling with the baby.

Earlier that month, Roger let his fans know of his impending fatherhood with a post on his website.  He wrote, “Mirka and I are excited to let you know we will be parents that summer.  Mirka is pregnant and we are so happy to be starting a family together.”
