Reinhardt announced to Britain’s Mail on Sunday that he has every intention of marrying the celeb heiress.
"I am going to ask her to marry me but I can’t say when. I don’t want to ruin the surprise," revealed The Hills actor, who wants to save a little suspense for the big moment.
The rumour was confirmed by a close source to the lovebirds, who stated, "They have been dating for five months and Doug has already said he’s going ask Paris to marry him in a couple of months. He doesn’t see the point in waiting around. He will ask her to marry him this summer."
If Hilton accepts, it would be her third engagement since the proposals of Jason Shaw and Paris Latsis, with whom she split in 2003 and 2005, respectively.
