It looks like it's a baby girl for US celebrity Kim Kardashian and her rapper boyfriend Kanye West. Or does it?

The couple was keeping silent yesterday in the wake of numerous reports that Kardashian gave birth over the weekend - about a month premature.

But Kardashian's sister Khloe appears to have let a rather cryptic cat out of the bag on Twitter.

"I can not even begin 2describe the miracle that is now apart of our family. Mommy/baby are healthy &resting. We appreciate all of the love," she tweeted yesterday.

She quickly followed with a second tweet: "More info will come when the time is right! Thank you all for understanding! We love you all dearly! Overwhelmed with love right now."

Kardashian's mother Kris Jenner linked to both tweets on her Twitter account, then wished West a Happy Father's Day.

Asked for comment on the red carpet at the Daytime Emmys, where she was a presenter, Jenner said, "she's in charge," pointing at her publicist who whisked her away from reporters after doing TV interviews.

The reality TV star's pregnancy was almost as anticipated as the royal pregnancy of Kate Middleton, who is due in mid-July. That is about the time the Kardashian baby had been due.

The 32-year-old has often been photographed since announcing she was pregnant, opting to continue to wear designer clothing. She said in April that she eventually embraced being an expecting mother after getting past "the awkward phases and stages".

The couple had initially kept the baby's gender a secret, but the sex was revealed earlier this month during one of Kardashian's doctor appointments on the reality TV show Keeping Up With The Kardashians"
