Hilton claimed her boyfriend was at home concentrating on his studies at the University of Southern California, saying, "He's meeting me here in a little bit. He's studying. He has a 12-page paper due this week.
"He's turning 21 in two weeks, so he wants to get all the work done before the big birthday."
The 25-year-old rubbished reports that there is trouble between the pair revealing, "We just got back from the Bahamas. We just got back two hours ago.
"We've been relaxing for the past five days."
