Former Spice Girl Mel B has not spoken to members of her family for two years, her sister has claimed.
Danielle Brown told OK! magazine that she checks her older sister is "OK" by following her on Twitter.
The 30-year-old, who recently had a second baby, said: "I don't even know if she's aware I've had a baby. Mel hasn't spoken to any of our family or friends in the UK for over two years."
Brown said she had not heard from Scary Spice, who lives in Los Angeles, since having a difference of opinion about Mel B's film producer husband, Stephen Belafonte.
The former Emmerdale star claimed: "I don't have her number, I don't know where she lives - I wouldn't know how to get in touch with her."
Mel B, who chronicled her life in The Mel B Project, a reality TV series which was broadcast in the US last year, recently denied divorce rumours.
