You probably thought the pairing of Michelle Williams and Jason Segel couldn't get any cuter. You were wrong. On Friday, the actor was snapped carrying an iPhone decorated on the back with photobooth pics of the actress. Surrounding the snaps were the words "I love you." Adorable, to be sure, but also a clear sign that things are getting serious. The reason? Segel taped Williams' pictures over his Beaker iPhone case, a true commitment for the star and writer of "The Muppets." See the pics here.
