Reality TV mom Lisa Gastinaeu has been diagnosed with skin cancer. The socialite's daughter and "Gastineau Girls" co-star Brittny broke the news at the launch of her new jewelry line in Los Angeles on Thursday.

She told, "My mom can't be here right now. She has skin cancer so just had surgery."

And Brittny insists the family has been left stunned by the news: "My mum was diagnosed with Melanoma in 2006. Since then she has always had to check her skin. She had her basil cell removed from her nose in October so her surgery is reconstructive. She is fine, everyone is good. She is so tough, she really is the toughest woman ever. She is so inspirational to me."
