The socialite - who ended her 14-month romance with reality TV star Doug Reinhardt in April - insists she just wants to be on her own and have fun.
In an interview on `The Ellen DeGeneres Show`, she said: "I don`t really want to date anyone yet. I just want to hang out with my friends and my family and enjoy life and focus on my work."
Despite her single vow, the 29-year-old star admitted she enjoyed having dinner with her ex-boyfriend Jason Shaw - who she dated from 2001 to 2003 - last week, and hinted something romantic could happen between them again.
She added: "I was with someone I was with, like, years ago back in the day. We`ll see what happens. I love him so much. We`re very close and I`ve known him a very long time."
