Did Monica?? (spoiler)

After Kevin and Monica broke up she went to LA with Chicago. In the hotel room they show her starting to give him a lap dance and making out with him. The the scene cuts off. The next scene of them is the next day and her in a bathrobe. Did they ever make it clear whether she had sex with Chicago or not? I'm assuming that he did because he put her on a monthly allowance the next day like the other girls he has had sex with and he started to show his true side by treating her badly. Does anyone know a definitive answer to this question?
