Rihanna

Enjoying an evening on the red carpet, Rihanna attended the UK premiere of "Inglourious Basterds" at London’s Odeon Leicester Square on Thursday (July 23).

Looking sexy in a lovely Alexander McQueen outfit, the "Umbrella" hitmaker posed for pictures and mingled with fellow guests at the high-profile event.

As previously reported, Rihanna has been making the most of her stay in London – enjoying a night out with Jay-Z earlier in the week.

According to insiders, the pair racked up quite the hefty bill at swanky nightspot Vendome – owing $16,000 when the night was over.
