Marg Helgenberger will end her "CSI" career with a bang this season.

The 51-year-old, who split from her husband the previous year, is dating again -- both on screen as Catherine Willows and in real life.

"I have a new boyfriend who's not in the business," she tells TV Guide Magazine. "Life imitates art because Catherine has her boyfriend as well [Detective Vartann, played by Alex Carter]. And I just heard that we are going to have a love scene together -- in bed. I haven't done that since George Clooney in 'ER.' I'm going to have to worry if my legs are shaved!"

Helgenberger had initially wanted to leave after 10 seasons, but is staying on for one more ever since her divorce.

"My ex-husband and I are on very, very good terms, but the way the money was divided certainly had something to do with me deciding to come back for another season," she says. "Yes, it's been a very lucrative job for me, so this wasn't something I financially had to do. It was something I wanted to do to build up my savings a bit more."

As for how she'd like her character to be written out of the show, she adds, "I certainly would not want to die and have my body autopsied."

"CSI" returns on Thursday, Septermber 23 with a premiere guest-starring pop star Justin Bieber.
