Caroline D'Amore

Paris Hilton is on a mission to change her ways. As we reported yesterday the heiress hired a crisis manager to clean her repertoire which has gone downhill since the last season of “The Prison Life.” Seems like the manager is paying off, because Paris looks like a changed woman.

We spotted Paris last night at Alex Quinn's “Dialed in With Blackberry Party” at L.A. HotSpot Opera. Paris arrived with her sister Nicky Hilton and friends. They hung out in the VIP section for a short time and bolted. There was no hard drinking or table dancing for the heiress. Paris was dressed conservatively with her knee length dress and a bow headpiece. The only exciting thing Paris did was play with her own Blackberry.

We also spotted newly engaged model/DJ Caroline D'Amore, who took over the turntables and rocked the house. Caroline showed us her beautiful vintage engagement ring, which once belonged to her fiancé Matthew Ross' grandmother. They seemed like such a genuine couple, they're both really down to earth.

Other stars at the party were “The Real Housewives of Orange County” stars Jo De La Rosa and Slade Smiley. Jo told us that she will be launching her debut album at the end of this year so stay tuned for that.
