Rehab fears for Rihanna
Could Rihanna be on the road to rehab?
The party-loving singer shocked fans last week after posting a Twitter picture of herself on a hospital drip, following an all-night bender at New York's Met Ball.
The singer later suggested she was at a private medical centre after being worn out by a bout of flu.
However, it's escalated fears that Ri-Ri, 24 - pictured barefaced in NY last week - is overdoing the partying.
She enraged Saturday Night Live bosses two weeks ago by missing a rehearsal due to illness and tiredness.
Last month she was pictured cutting up white powder off a friend's head at the Coachella Festival.
