(Caroline Greyshock)

Since announcing her surprise pregnancy to OK! last December, Jamie Lynn Spears has become no stranger to crazy, unfounded headlines.

First, the gossipers said she'd miscarried, but the June 19 birth of Maddie Briann proved that one wrong.

And then they said she'd been cheated on by boyfriend Casey Aldridge, a claim he strongly denies in an exclusive interview in the new issue of OK!.

Now comes a wild report that the 17-year-old is pregnant again! Well, if that's true, it's certainly news to Jamie Lynn – her rep confirms exclusively to OK! that those rumors are false.

"She is not pregnant," her rep rells OK!.

When OK! spoke to Britney Spears' little sister for our exclusive cover story, we asked if she and Casey were planning to expand their brood anytime soon.

"You're way ahead of yourself on that one!" said the former Zoey 101 star, who has her hands full as it is with nearly 4-month-old Maddie.

"We are really happy with where we are right now," explains Jamie Lynn about her relationship with Casey. "There is no rush for anything."
