Justin Timberlake is giving his bedroom a major overhaul after GF Jessica Biel refused to boink him on the same old mattress he previously used to bed his once infamous harem of hotties.

“Now that they’re practically living together, she didn’t want to sleep on the same bed as his old girlfriends,” a friend of the couple reveals to Star Magazine.

Now that J.T has purchased a new Select Comfort mattress “Jessica’s sleeping a lot better!”

Does it really matter? What do you guys think about this type of thing?
