'No, I don't have a butler', says billionaire's daughter Pegula

Jessica Pegula says she finds it "annoying" and "outrageous" that fans believe she has servants waiting on her hand and foot just because her father is a multi-billionaire sports mogul.

American star Pegula is an accomplished professional tennis player in her own right, and on Monday showed off her credentials by reaching the quarterfinals of the US Open.

However, the 30-year-old has found it almost impossible to separate her fortunes from those of father Terry Pegula, who owns the Buffalo Bills NFL team and the NHL's Buffalo Sabres.
