Paris Hilton and Benji Madden were on hand last night for the WBO Championship fight between Kendell Holt and Ricardo Torres. The world super lightweight event was held at Planet Hollywood hotel and casino in Las Vegas.

Paris appears to have on a sheer lace dress bodice in these photos. The keyhole gives the world a glimpse of the girls huddled together. Is it our imagination or is she giving them a boost with a subtle squeeze of arms, which appear to be held firmly against her body?

At any rate, they were not the only celebrities taking in the action. Mike Tyson and Steve Lawrence were also photographed ringside.

It was a busy day for Paris, who also took in boyfriend Benji’s performance with Good Charlotte Good Morning Revival. The band rocked poolside from 7:00 p.m. until 3:30 a.m. at Hard Rock Hotel and Casino.

Check out the rest of the photos below.
