Kaley's first real movie gig was in the 1995 movie, "Virtuosity", playing Karin alongside Denzel Washington. She later did a cameo with the biggest star in Hollywood, Jennifer Aniston, playing the little girl in the movie, "Picture Perfect." She later starred in many TV movies, but what got her noticed was her role on "Ladies Man." She joined the cast in 1999, as Bonnie Stiles. However, the show ended in 2001.

After tons of auditions, and tons of rejections, Kaley got a surprise in the spring of 2002... her cell phone rang shortly after meeting the producers of "8 Simple Rules." "The phone rang and my manager was like, 'You're Bridget!'" Kaley recalls, still very excited. "I was so excited! I waited so long for this to happen."

Kaley plays Bridget Hennessy, a blonde kind of air-headed girl who gets by on her looks. Amy Davidson plays her TV sister, Martin Spanjers plays her TV brother, Katey Segal plays her TV mom, but the real prize was her TV dad, John Ritter. "I had already been cast on '8 Simple Rules For Dating My Teenage Daughter' when John Ritter signed on to play my dad. At first I thought, 'Are you kidding me? The Three's Company guy?' It was supposed to be John Goodman. I've taped sitcom pilots that went nowhere, and I was sure this was another dud. But the second I met John, I knew I'd never been more wrong... the first thing John said to me was, 'Isn't your shirt a little too revealing?' I couldn't tell if he was serious or if he was just playing the part. But everyone laughed; he got us joking around like family right off the bat. In fact, working with him rarely felt like actual work. His main goal was to make people smile."

After the first season ended, things were looking good for the new hit TV Show... it ended up being signed for another season! As they took a break from taping the new season, they would go to John's favorite place, Disneyland, and during that time, Kaley was dating actor Kevin Zegers, and of course John had to approve of him before she would date, and he knew he was a good person. Things were looking good for Kaley as her stardom was becoming better by the day. She appeared on the cover of TEEN, but of course this was not the first time Kaley has been on the cover of something. In 2001 she was on the TV Guide with other young new actors and appeared on USA Newsweek in 2003. In early August she went back to ABC to start shooting season two of 8 Simple Rules, and they completed three episodes for a September premiere. But as they were rehearsing on September 11, 2003, John didn't feel so good so he left to go take a nap. As Kaley was rehearsing, she saw John and asked if he was okay, the actor replied saying, "Do you know how much I love you?" and she replied, "Well yeah I love you so much too."

"I went home, went to dinner, had a great evening, Martin called me, he goes, 'I think John has the flu, we're not going to work tomorrow.' So my first thing was 'Three day weekend!' I was so excited, literally this happened in a matter of 15 minutes, 5 minutes later my producer called and said 'Kaley, I just want you to know it's a little more serious than the flu; but, everything is fine, he's going into surgery.'" Sadly John Ritter passed away during surgery, he was only 54 when he died. Kaley was shocked and very heart-broken, and she didn't want to go on with 8 Simple Rules because she felt it was more of the Ritter Show. After months and months of thinking, she decided to continue the show. They aired the first 3 episodes and took a long break and then worked on the Goodbye episode, and tons of fans tuned in to say goodbye to the late great John Ritter.

Kaley would soon be talking about her late TV dad on TV talk shows and one of the most watched news shows on CNN, Larry King Live. It was soon to be that Kaley would be more noticed from the death of John. Kaley would soon join up for new upcoming roles for ABC and NBC, and she just completed an NBC mini series 10.5, she also completed a movie with BSB Nick Carter and ex-boyfriend Kevin Zegers. She also has an upcoming cartoon coming up, 8 Simple Rules is a big hit, plus she's got more movies on the way. Kaley is starting to become a well-known actress, and we know she will be a huge star.
