Hilary Duff and Mike Comrie leaving Trousdale nightclub in Hollywood (5/7)

Remember how awesome it was when Hilary Duff and Mike Comrie got engaged in February? *makes blowjob motion with hand and mouth* It's been all downhill since then. From Star:

Hilary Duff and Mike Comrie are hitting some major speed bumps on their journey to the altar! The pair, who got engaged in February after two years together, have been increasingly butting heads, and had a particularly nasty spat while at L.A. nightclub Voyeur on May 28. "Hilary and Mike were yelling at each other in front of a bunch of friends," says a source. "She got so annoyed at one point, she stuck her hand in his face to shut him up."

The couple's problems seem to worsen when Edmonton Oilers player Mike, 29, and Hilary, 22, have a few drinks out a night, the source adds. "Mike can get pretty jealous, and has a temper. They get along much better during quiet evenings at home." (Print Edition - 6/21)

Hilary better be careful when arguing with Mike. If there's one thing hockey players know a lot about, it's knocking out teeth -- and Hilary's mouth poses a pretty easy target. If Hilary wants this relationship to last, she's going to have to find a way to calm Mike's temper and keep him docile. The best way to do that with any professional athlete: give him a coloring book.
