Check out rihanna's pix during the London new film promotion 'Battleship"

Rihanna

The Good Girl Gone Bad singer Rihanna, who makes her acting debut in Peter Berg's action adventure, donned an olive-green silk Grecian-style dress and pointed court shoes for a photocall with co-stars Taylor Kitsch and Brooklyn Decker.

Brooklyn, meanwhile, opted for a more daring monochrome dress with revealing cut-out panels.

Rihanna showed off a more sophisticated look while in London promoting her new film Battleship - just hours after she hopped on the Tube in hotpants and thigh-high leather boots.

The event at the Corinthia Hotel comes after Rihanna was spotted using the London Underground to get to the capital's 02 Arena, where she watched her rapper friend Drake perform.
The star - who has recently been linked to Two And Half Men's Ashton Kutcher - went for a raunchier look for the gig, in a flame-printed T-shirt, cut-off denim shorts and thigh-high leather boots.
It's not the first time Rihanna has used public transport to get to the venue - she took the Tube to a Brit awards rehearsal last month, and last October made her own way to her O2 concert surrounded by commuters.
