Paris Hilton, who famously appeared in an commercial for Carl's Jr. Burger last year, is giving up her junk food habit.

She explains, "I've been really working out. I'm not eating fast food anymore. No more McDonald's. (I'm) getting my bikini body, so I'm about that." 

Paris recently confirmed she's dating her ex-fiancé Jason Shaw, but the couple is taking it slow.
The socialite and her ex were spotted out in Hollywood last month, prompting speculation she had found love again after splitting from on/off boyfriend Doug Reinhardt last month. And Hilton admits she has feelings for Shaw, who she was briefly engaged to in 2003.
