Penelope Cruz Joins Christina Aguilera For Engagement Celebration  5/6/05

Christina Aguilera partied with neighbor and pal Penelope Cruz recently, when they celebrated the singer's engagement to Jordan Bratman.

DIRRTY singer Aguilera booked Santa Monica, California's Buffalo Club for the bash, where her fiancé got some wedding-day practice by carrying the blonde star over the threshold of the restaurant.

Approximately 100 guests - seated at tables featuring rose petals and mini wedding cakes - toasted the couple, including Cruz's boyfriend Matthew McConaughey.

The party also marked the first time that Aguilera's Philadelphia-based family met with the Bratmans.
