Doctors at Macclesfield Hospital halted her contractions with medication and will decide in the next 24 hours when she will be induced.
The 27-year-old was believed to be in the middle of filming the final episodes of her controversial MTV fly-on-the-wall show, Crazy In Love, when her contractions began on Wednesday night.
The drama was thought to have been caught on camera even though she had reportedly decided to pull out of the show.
The couple already know the baby is a boy and are planning to call him Max.
