Gary Goldsmith, uncle to Princess Kate Middleton, has joined Celebrity Big Brother, causing a stir by discussing private royal family matters.

Goldsmith revealed Kate's recent abdominal surgery and her expected return to royal duties after Easter, without royal family permission for his TV disclosure.

His participation on the reality show is controversial, especially with Women's Aid criticizing his involvement due to past domestic violence incidents.

Speculation arises from the lack of recent paparazzi photos of Kate, post-surgery.

Sharon Osbourne, a fellow contestant, has referred to Goldsmith as an 'oddball,' while he continues to make remarks about the royal family.

As Princess Kate recovers from surgery amidst family drama, there are concerns about further private information being revealed by Goldsmith on the show.

Celebrity Big Brother featuring Goldsmith airs on Virgin Media Two and ITV.
