According to reports, the American was taken to the emergency room at Cedars-Sinai hospital in Los Angeles on Tuesday, 20 January.
It's thought Mel B took him there.

The former Spice Girl admitted that she and Stephen don't have a lot in common but their relationship still works.
Mel is now in London to attend the National Television Awards at the O2 Arena tonight, where X Factor has been nominated for an award.
Stephen, meanwhile, has been on daddy duties back home in the US and this morning shared a sweet image of himself and three-year-old daughter Madison to Instagram.
"Moments like this make my heart melt from pure love," he captioned the picture, adding the hashtags 'Daddy's little girl' and 'They grow up too fast'.
