We were so proud of Britney Spears and Kevin Federline when they christened little Sean Preston. Not only did they avoid going too personal with the moniker (Frappuccino Ferrari Federline, anyone?), but they also stayed away from career-limiting labels so often favored by celebrities (we're looking at you, Pilot Inspektor Lee).

But will their second offspring not be so lucky?

So claims Star magazine (via the New York Daily News), which says Mr. and Mrs. K. Fed plan to give their newest bundle of joy, believed to be a girl, a name that at best will result in playground teasing from Apple and Suri and at worst might foreshadow some time spent in solitary confinement.

The alleged appellation? Jailynn, an homage to Britney's parents Jamie and Lynn, and her doppelganger sister, Jamie Lynn.

And it seems the tabloid has Spears' OB-GYN on speed-dial, because it posits that she'll deliver the ankle-biter by Caesarean section on Sept. 14, which also happens to be Sean P.'s first birthday. (If you're looking for the perfect gift for the chubby-cheeked tot, we suggest a few therapy sessions to help him work through that whole sibling rivalry thing.)

But don't order those "Jailynn"-embroidered wife-beater T-shirts and micro-mini-skirts just yet. Despite Britney reportedly indulging in several pink-filled shopping sprees, she recently stocked up on "boy booty" at fancy-schmancy L.A. baby boutique Petit Tresor, says the Daily News.

Us Weekly, however, insists the down-market duo still doesn't know whether it's a boy or a girl (they've apparently picked out names for both and have decorated the nursery in neutral hues), and pinpoints Britney's delivery date as Sept. 7, which is right about ... now. Stay tuned.

Meanwhile, as Britney finishes incubating the couple's latest contribution to the gene pool, Kevin continues to push his music career. On Wednesday, he sat down with talk-show host Ellen DeGeneres to discuss what life is like as the much-mocked would-be rapper-husband of an erstwhile pop starlet.

"I would be lying if I didn't say it was tough," admitted Federline, who once again performed the brain scrub-inducing ditty "Lose Control." "I think the expectation is real high for me, you know. It's like you see my wife, here she is this huge superstar, everybody loves her, all of her music is just hit, hit, hit after hit, and it's hard to compete."

But he seems to be keeping his delusions of grandeur somewhat in check: "I don't see it as a competition. Maybe other people are putting it in that perspective, but I don't see it like that at all. I just have fun. I love rapping and making music. Period."

As for his swelling wife, he says her cravings with this pregnancy haven't been "too bad," except for wanting "ice chips all the time," an indulgence he confesses he doesn't understand. (And because we're nothing if not helpful, a quick search of "craving ice" reveals that perhaps the Britster should have her iron levels checked.)

And don't forget to TiVo Kevin's sure-to-be memorable acting debut as a teenage toughie on "CSI: Crime Scene Investigation" next month, a performance he rates as "pretty good."
