After a technical submission loss to top contender Jeremy Horn shortly after, Liddell began establishing his reputation as a top contender with dominant victories over Kevin Randleman, Murilo Bustamante, Vitor Belfort, Amar Suloev, Jeff Monson, Renato Sobral and Tito Ortiz.
Liddell was also the first UFC fighter currently on the roster to go fight in Pride where he represented the organization against fellow kickboxer Guy Mezger, knocking him unconscious.
While growing up in Santa Barbara, he often frequented the infamous Del Playa Drive, the middle of the party scene of the college town of Isla Vista, where he often found himself in fights with drunk college students.
He became a Division I wrestler at Cal Poly (California Polytechnic State University) in San Luis Obispo California Liddell made his UFC debut in 1998 during UFC 17 in Mobile, Alabama with a decision victory over Noe Hernandez.
Since UFC 47, the bad blood between both fighters remained, with Ortiz repeatedly stating that he wanted "his" title belt back.
Despite the tension, Ortiz and Liddell would not fight again for two and a half years.
Later in the second round a visibly exhausted Liddell was taken down and received a barrage of punches from the ground.
His corner threw in the towel, giving Jackson the upset victory.
The UFC tried to arrange a title bout with then-champion Tito Ortiz, but Ortiz cited scheduling conflicts.
Smirnoff and Penny met through a mutual friend, UFC fighter Chuck Liddell.
'I'm the happiest I've ever been and Brad is the sole reason for that,' Smirnoff told US Weekly at the time of her engagement.
He has an extensive striking background in Kempo, Karate, and Kickboxing, as well as a grappling background in collegiate wrestling and Brazilian jiu-jitsu.
Liddell was born in Santa Barbara, California, of Irish descent.
