Even though Hilary Duff and Mike Comrie enjoyed a beautiful fun in the sun vacation in Hawaii last week, where Hil showed off her bikini body - it seems the couple actually didn't get all that much sun!

Whether it's because they're cautious about skin cancer, or they were enjoying more of each other's company than the sun's...Eonline.com outed the couple's fake tan!  

Right after returning from a sexy Maui vacay, the pale pair were tanned, airbrush-style, at Hil's Toluca Lake house with Fake Bake, which makes emergency house calls to the stars!

Well it's better off, skin cancer is no joke, at least their skin will be healthier for it.   I would totally do the spray tan if I didn't come out looking so orange, or unless I had the money to have a celebrity tanning service spray me up!
