My Bestfriend's Girlfriend (2008)

After an awkward yet memorable encounter at a stag party, Evo (Richard Gutierrez) and Grace (Marian Rivera) thought they would never see each other again. Little did they know that Grace is actually the girlfriend of Evo's best friend Mark ('JC de Vera'). Ever the arrogant player, Evo takes advantage of what happened at the party to make Grace agree to his demands and forces her to pretend to be his girlfriend to make his ex Akiko (Ehra Madrigal) jealous. Will it work too well?
