Rihanna Does Slob Chic As She Leaves London Hotel (PICS)

It looks like Rihanna is finally running out of skimpy things to wear.

The singer was spotted leaving her London hotel yesterday rocking some serious slob chic as she dressed down in a grey tracksuit.

Yep, there really was no see-through bra, no short hot pants, no t-shirts emblazoned with swear words - just a pair of jogging bottoms and a hoody as she headed to a recording studio.

Wonders really will never cease.

RiRi is in the UK following her performance at Radio 1's Hackney Weekend on Sunday and after jetting around Europe for a string of gigs, she'll return to play Wireless Festival in Hyde Park on 8 July.
