London: Eccentric star Lady Gaga thinks that Paris Hilton is 'plain' and 'very, very boring'.
The Poker Face hitmaker went to the same strict US convent school as Paris, and sister Nicky.
Gaga described the Hiltons as "well-behaved and neat — a total contrast to myself," reports the Daily Star.
Paris, however, has said that she is a huge fan of the singer.
