Hollywood heiress Paris Hilton has a new BFF: Manny Pacquiao.

The hotel heiress spent this week taking care of business in the Philippines, and part of her trip included a dinner party hosted by boxing congressman Manny Pacquiao and wife Jinkee at a boogie hotel. Pacman gave Paris a shirt with his likeness on it, and Hilton later wore it proudly.

Pacquiao developed a friendship with the socialite a few months ago, around the time he fought Shane Mosley.

Hilton's five-day journey was set up through a real estate company that hired her to help design and shoot an ad campaign around its new Paris Beach Club.

The socialite was seen by the Manila Bulletin at the Ninoy Aquino International Airport wearing the gift. Hilton later tweeted that the boxing star gave her the shirt.

And you thought Paris had the bigger ego. Who hands out T-shirts with his name and photo as gifts to guests? Pacquiao definitely wins this arrogance battle. (Though we don't know if Pacman wore Paris' perfume.)

Despite being named on the same list with Casey Anthony and O.J. Simpson of America's Most Hated Celebrities, Hilton drew a crowd of more than 5,000 people in Manila, according to the Philippine Star. The crowd reportedly started lining up three hours early to catch a glimpse of the D-list Hollywood star's appearance at a mega mall.
