Jenna Parties with UFC Fighter Tito Ortiz

Jenna Jameson celebrated with UFC superstar Tito Ortiz at his official after-party Saturday night at Tryst inside the Wynn Hotel in Las Vegas.

Jameson, along with Club Jenna's Linda Johnson, sat in the front row for his grudge match with Ken Shamrock at UFC 61: Bitter Rivals at Mandalay Bay. Ortiz stopped Shamrock in 78 seconds in the highly anticipated, light heavyweight fight that took place before a sellout crowd of 12,000-plus. The bout was a rematch of their 2002 fight that Ortiz also won.

The starlet is friends with Ortiz and predicted a victory for the Huntington Beach fighter several hours before the bout started.

Then on Sunday, Jameson hosted the launch party for Silicone Sundays at Ivan Kane’s Forty Deuce nightclub at Mandalay Bay.
