US heiress Paris Hilton has reportedly got engaged to boyfriend Doug Reinhardt, after she thanked her "future sister-in-law" at a charity event.
The socialite sparked rumours that she has accepted a proposal from former `The Hills` star Doug when she accepted an award for her charity work over the weekend, E!Online reported.
During her speech at the Hearts for Hope benefit here, she said, "I`d like to thank my future sister-in-law Casey Reinhardt."
If Doug, 24, has proposed he needs to look no further than his mother for inspiration for a wedding ring.
"At one point, Paris reached for Doug`s mom`s huge wedding ring. She looked like she was in awe," a source added.
Paris, 28, has made no secret of the fact she wants to get married this year.
Speaking about Doug, she said last month, "I wouldn`t rule out a wedding in 2010. With how amazing everything is going between us, I see a very bright and happy future.
"He`s taught me how real love can feel. Doug`s taught me how to grow up and become more domestic, as in not going out as much as I used to."
Doug, who reconciled with Paris last August following a brief split, is also completely smitten with her.
"Paris is the most beautiful girl in the world. She is gorgeous, smart, funny and kind. My family loves her, and she would make the perfect wife."
