Private Practice is about to get a whole lot McSteamier.

As you probably know by now if you're a fan of the ABC Grey's Anatomy spinoff, somebody from that show is traveling to L.A. from Seattle to appear in an upcoming episode.

That someone has ties to star Kate Walsh (Addison).

“You’ll get a taste of what you love with Addison and Sloan [Eric Dane],” Kadee Strickland, who plays Charlotte, told TV Guide. "We know their relationship is never simple."

Their relationship, as well as the upcoming crossover is, however, "always fun to watch. They have great chemistry together. It’s really cool having him come over.”

What was it like having Dane on their set for a change?

“He kept saying, ‘Everyone’s so nice!’ I think it’s great, You never know, because he has his home [at Grey’s Anatomy]. I’m sure he feels safe and nice there and now he gets to come over. It’s like he just changed schools. He’s a very sweet man.”

The crossover is believed to center on Mark's teenage daughter, played by Leven Rambin, who revealed herself on last week's episode of Grey's. She also revealed that she's pregnant, a possible tie-in with Mark and neo-natal surgeon Addison.

As for Charlotte, Strickland loves where her storyline is headed.

“This whole sexology thing that I get to do? It runs the gamut from trannies to sexual dysfunction. I have tons of stuff to play with. I can’t wait!”
