Benji & Paris Keep Their Lips Locked

As their relationship becomes increasingly public, Paris Hilton and Benji Madden are going to be facing a lot more queries about those lingering engagement rumors - but somehow, we don't think these two are going to crack!

Yesterday, we caught the two lovebirds walking to their car and posed a few questions about their alleged engagement. Unfortunately, neither Paris nor Benji was willing to let a loose word slip - guess they're playing coy!

Oh well - the couple that stays quiet together, stays together!
