The 38-year-old singer said on a radio station that as her daughter Angel was not feeling very well, she took her to the emergency room, reported Us magazine.
"This morning's been a little bit crazy because my six-year-old, Angel, was feeling not very well yesterday. She was a little bit dizzy and had her first ever nose bleed, so I kept her off school.
"And then this morning, she woke up completely disoriented and blood was just funneling out of her nose like no tomorrow. So I rushed her to the emergency room -- I just literally left there like half an hour ago. She had blood tests, she's got like a heart murmur thing on -- poor little thing," she said.
The British singer is also mother to daughter Phoenix, 14, with ex-husband Jimmy Gulzar, and daughter Madison, 2, with husband Stephen Belafonte.
