Well who would’ve thought it, Mariah‘s gone all demure on us. The Precious star has kept her trademark cleavage under wraps tonight (by her standards), with an elegant midnight blue gown by Valentino. The capped-sleeve style was seen on a number of guests tonight, including Carey’s co-star Mo’Nique, who also looked radiant in blue.

But Ms Carey hasn’t disappointed on the bling front, accessorising with jewels by Chopard and a chunky statement watch. “I don’t usually wear one, because I don’t care what time it is,” she told Sky1′s Angela Griffin. “I run on Mariah time”.

The star later caught her bling on American presenter Ryan Seecrest as she cruised down the red carpet – in Mariah time, that translates as embarrassment o’clock.
