Lindsay Lohan, John Mayer, Willie Nelson and Justin Bieber all got a David Letterman mocking during his Top 10 Surprises at the Grammy Awards Sunday night.

No. 10 “Lindsay Lohan seen leaving the Staples Center with a Grammy-shaped bulge,” he joked. The actress is currently free on bail with a felony grand theft charge.

No. 9: “New music laws prohibit rhyming ladies with Mercedes.”

No 8: “Willie Nelson provided the Grammy show snacks.” Nelson was arrested in November for pot possession.

No. 7: “Jay-Z revealed ‘Empire State of Mind’ was really about Trenton, New Jersey.”

No. 6: “The new category: best male or female traditional R&B urban alternative non classic latin performance by a duo or group with vocals.”

No. 5: “In a touching ceremony, will.i.am added a comma.” The Black Eyed Peas member laughed at the joke when cameras panned to him after.

No. 4: “The Academy president finally explains the difference between record of the year and song of the year.”

No. 3: “Lady Antebullum and Lady Gaga form supergroup Lady Antegagum.”

No. 2: “John Mayer caught in a passionate embrace with Susan Boyle.”

And No. 1 “Justin Bieber? Hair piece.”

Justin Bieber seemed to miss the joke when cameras panned to him, but his buddy Usher laughed.

With the right 33 year-old, and the right 21 year-old the age difference wouldn’t be so creepy. But with serial dater  John Mayer boinking the 90210 ditzy actress..this skews like EWWWWW.

Mayer’s womanizing seems to be getting more unscrupulous as the years go by. He started off dating chicks his own age, respectable actresses with a bit of sense. (Minka Kelly..Jennifer Love Hewitt…Jennifer Aniston) then moved on to young girls not quite sure of themselves that believe every guitar player with his heart on his sleeve. (Jessica Simpson, Taylor Swift and now Shenae Grimes)

Another reason to dislike John The Playa Mayer. If you can believe the lyrics to a teenage girl pop song..he is pretty much a creepy old man.

Taylor Swift performed a few of her new songs in Paris last night and this one titled Dear John says it all.

“Dear John/I see it all now that you’re gone/Don’t you think I was too young/To be messed with/The girl in the dress/Cried the whole way home/I should’ve known.” Later, Willman reports that the second chorus finds Swift singing: “It was wrong/Don’t you think nineteen’s too young/To be played/By your dark, twisted games/When I loved you so.”

Could be a case of a creepy older dude hitting on a barely legal teenager…or could be a silly teenage girl reading way too much into an older paying her some attention.

The recent hook-up in Atlanta and the end of John Mayer’s Twitter addiction could all be signs that Jennifer Aniston and John are back together.  OK! magazine claims it has a credible source that says Jennifer thinks that John is the love of her life, not Brad Pitt as most people think.

I’m less convinced by OK!’s source than I am by the fact that JM deleted his Twitter account…not just stopped posting…he deleted that mother! And ya’ll know what a Twitter ‘ho he was.

“Jen feels it was actually John who was the life of her life and the one who got away,” the pal reveals to OK! of Jen and John’s latest reunion.

On again / off again. That’s the way Jennifer Aniston and John Mayer roll. The two friends (with benefits) hooked up in Atlanta this weekend. John was in town for a concert and Jen is filming Wanderlust close by with Paul Rudd.

Jen was in work-out clothes and had a baseball cap pulled low over her face when she visited with John backstage after his performance, a source tells RadarOnline.com. “She looked gorgeous and seemed to be really enjoying herself. She and John laughed a lot.”

Afterward, Jen and John and several people connected with his tour all went back to her hotel, The Ritz-Carlton, where he rented a private suite for an impromptu party. John moved on to his next tour stop, Tampa, Florida, the next day. Jen is in Atlanta for several more weeks filming Wanderlust with Paul Rudd.
