Hilary Duff graces the cover of Maxim Germany for its May 2009 issue. Although you don’t get to see Duff in the tabloids often, this 21-year-old is keeping busy with different things, from acting to singing and her business ventures. Plus, she’s got a stud of a boyfriend, so Hilary might as well be on the top of her world.

Hilary Duff started dating NHL hockey pro Mike Comrie in 2007 and they have been inseparable ever since. For Duff’s 20th birthday, Comrie bought her a Mercedes-Benz for a birthday present. Duff is often seen on Comrie’s games, supporting her man.

Aside from her relationship, Hilary Duff will also be seen on her upcoming film, “What Goes Up” and will probably be doing promotion work for the film in the next few weeks.

As for her business ventures, Hilary has expanded her “Stuff by Hilary Duff,” brand, a clothing line she launched in March 2004, by adding jewelry and furniture collections.  She has also released her own perfume, “With Love… Hilary Duff”.
