Talk about a sticky situation.
Celebrating the U.S. premiere of her sci-fi film Battleship
at its after-party Thursday night, Rihanna
passed on a plate of two hot dogs, macaroni and cheese and corn on the cob for a decidedly less filling dinner: a stick of chewing gum.
Following the screening at Nokia Theatre L.A. Live (to which she arrived about 20 minutes late) the singer-actress, 24, kept it low-key, sitting at a table with her family, including her brother Rajad. Enjoying a lime cocktail, she also hung with actress Malin Akerman and posed for photos with fans and military guests before leaving at about 11:30 p.m.
Also celebrating: costars Taylor Kitsch, Alexander Skarsgard
, Brooklyn Decker (and husband Andy Roddick) and Liam Neeson.
