After Kevin Federline split with wife Britney Spears, he grew closer to his ex-girlfriend, Shar Jackson — so close that one magazine said she was pregnant with their third child. An upset Shar turned to In Touch to set the record straight. On June 22, the actress took two pregnancy tests at her manager’s office on Beverly Boulevard in LA — and both proved that she’s not expecting.

“What better way to document the truth than by taking a pregnancy test in front of America?�? Shar, 30, says in an exclusive interview. Besides offering the tests as proof, Shar points out that she “just spent $16,000�? on a tummy tuck. “If anybody thinks I’m ruining it by getting pregnant, they’re out of their mind!�?

Shar admits she has forgiven Kevin, 29, for leaving her for Britney, 25, when she was pregnant with their son, Kaleb, and that they see each other “all the time.�? She’s brought Kaleb and their daughter, Kori, closer to Kevin and Britney’s sons, Sean Preston, 21 months, and Jayden, 9 months. “We make sure they play together and know that they’re siblings,�? Shar says.

More kids with Kevin?

Although Shar says she’s not having sex with Kevin, she admits: “We still love each other. We’re going to be a part of each other’s lives for the rest of our lives.�?

And she doesn’t rule out having more kids with him in the future. “I can’t say yes or no,�? she says. “If I decide to have kids, it’s going to be with whoever I’m in love with.�? But the mother-of-four’s in no rush: “I might decide in eight years to do this again, but trust me, nothing’s happening before that. I’ve got to get at least eight years’ wear on this new stomach!�?
