First came love, now comes marriage...but are Katy Perry and Russell Brand already putting the carriage before the ceremony? Some cryptic Tweets make it seem like the engaged couple might already be with child. The kooky comedian proposed to the kooky pop singer while on holiday in India, and now that they're back, the avid Tweeters seem to have tongues wagging with posts that may indicate a bun in Katy's oven. To kick off the new year, Perry tweeted, "Let me tell you 2010 is BUMPIN!" Then last Friday, she wrote "Hey @rustyrockets I heard ur prego-ed" - rustyrockets is Russell Brand's Twitter name. Over the weekend, she tweeted about her need for an In-n-Out burger and demanded a picture of the hamburger chain's famous double-double animal style burger. Pregnancy craving? She then addresses Brand again, telling him "I love you... (awwww barf!)" There are some interesting references on Russell's Twitter page, too. Back on Dec.18, he replies to a friend, saying, "@PhilBattrick Mouth organ is equally good - providing it can be used to procreate a musical baby." Then on Dec. 26, he wrote, "Tonight I turned off my famous, hedonistic hot-tub, a monumental event. I did it for climate change. In every sense." Perhaps an effort to aid pregnancy? Cravings, bumps, procreating, barf...in a few months, we'll see if any of those references add up to a shotgun wedding for the pair.
