Jean Baptiste Lacroix/Getty ImagesParis Hilton isn't the only subject of boyfriend Cy Waits' affections.
Her man has also been spending time with another "beautiful blonde" every weekend in Las Vegas, we've learned.
So who's the other girl?
It's his 7-year-old daughter, Shae—and Paris couldn't be happier with the situation.
"One of the things I love about Cy is what an amazing father he is," Paris tells me. "I've become really close with his daughter."
Although Shae lives in Vegas, Paris and Cy go spend quality time with her every weekend.
"She is an animal lover, just like me," Paris says, "We love going to the pet store together to play with all the animals. We do fun girly things like getting our hair and nails done together. She's beautiful, blonde and full of personality."
A source close to Cy says he's very happy the two are getting so well.
"Cy is thrilled with how much Shae loves Paris," a source says, "He is very close with his daughter and it means the world to him that Paris is so amazing with her."
In fact, playing stepmom has made Paris want her own family soon.
"Being around Shae has really made Paris want children of her own," a source close to Paris says. "She told friends that she feels having a family is the meaning of life and how she can't wait to have a baby one day."
