Britney Spears has left her recent troubles behind her to holiday in Mexico with her paparazzo boyfriend ADNAN GHALIB. The Toxic singer, wearing a pink wig, and Ghalib checked into the Rosarito Beach Hotel, just south of the U.S. border, on Wednesday (09Jan08) afternoon. The pair are travelling with unidentified friends, according to Mexico's Ensenada newspaper. Last week (ends04Jan08), Spears was taken to Los Angeles' Cedars-Sinai Medical Center for a mental evaluation following a stand-off with police when she refused to hand over her boys to ex-husband Kevin Federline after a scheduled visit to her mansion.
