Is Britney Spears carrying twins?

Is pop star turned reality-TV diva Britney Spears expecting a dynamic duo in the delivery room?

So claims one report Thursday by New York's Daily News, which said Spears just learned she is expecting twins, though it couldn't confirm that with Spears' spokeswoman, Leslie Sloane Zelnick.

"If she's having twins, I have not been told that yet. Let me make some calls," Zelnick told the paper.

Spears, now 23, is also reining in the spending habits of 27-year-old husband Kevin Federline, one source told the paper. ""Kevin's on a leash," the source said.

Zelnick denied a claim by the same source that Federline isn't paying child support to the mother of his two other children.

Spears and Federline were recently seen on TV in their own UPN reality series, "Britney and Kevin: Chaotic," which featured footage of their courtship in Europe and their hastily planned L.A. wedding. Its mid-June finale featured a new Spears video and a video love letter from Federline to his wife.

The show, mostly a mix of taped interviews and home-video footage shot by the two lovebirds, was roundly panned by critics.
