See pictures of stars' Twitter photos.03.17.11 12:13 PM ETWillow Smith Continuing her tour with Justin Bieber, Willow Smith prepared for her London show last week. "London...here we come," she tweeted. After her shows, Smith had nothing but great things to say of her fans: "London, was sooooooo AWESOME!!!!! They made me feel like I am the only girl in the world!!" Then she tweeted, "dreams do come true :)" Kathy Griffin You may have seen the infomercials on these seemingly comfy "pajama jeans." The jeans that "looks like denim…but feels like PJs" appear to be a favorite of Kathy Griffin, too. She tweeted: "Pajama jeans!!!" Neil Diamond This past week, the Rock and Roll Hall of Fame inducted Neil Diamond to its list of revered musicians, which includes Bruce Springsteen and Rod Stewart. This year, Diamond shared the stage with fellow inductees Alice Cooper and Tom Waits before heading back to Australia to complete his tour. Diamond tweeted, "OMG! Now that I'm a Hall of Famer, they put me in charge of the plane!" Weird Al Yankovic Last year, the Australian airline Qantas debuted a safety video that shows a pilot-suited John Travolta, the airline's Good Will Ambassador, welcoming fliers aboard. When funnyman Weird Al Yankovic recently flew between Australian cities for shows in Canberra and Queensland, he tweeted, "OMG… the pilot on this flight is John Travolta!!!" Charlie Sheen This week, Charlie Sheen shocked us again when his tour, entitled My Violent Torpedo of Truth/Defeat is Not an Option sold-out within minutes in numerous cities, including Radio City Music Hall in New York. In this pic, Sheen makes reference to a recent tweet that one of his goddesses, Rachel, had, " left the building." Sheen responded: "#fastball; Told ya' she'd be back... Jealous face much..? Ybw c" Justin Bieber This past week, Madame Tussauds Wax Museum in New York unveiled Justin Bieber's wax doppelganger. And if it wasn't for the Bieb's new haircut, the pint-size performers might be difficult to differentiate. Bieber's mother stood between the two. The real Bieber tweeted, "knew @studiomama had more kids! me and my mom and lil bro." James Franco Now we see where James Franco gets his good looks. In this twitpic, a baby Franco sits in the kitchen with his dad, Douglas, who's wearing a stylish kimono. Franco tweeted, "Me and dad." Demi Moore The Purse Monkey phenomena of Demi Moore and Ashton Kutcher's may not have caught on as much as Travelocity's Roaming Gnome, or as even as quickly as Charlie Sheen, but it still seems to get around. This week, Purse Monkey was seen in Austin, Texas for the South By Southwest (SXSW) Festival. Moore tweeted, "Purse Monkey at #Diggnation Live," with a pic of Kutcher holding the little creature. Chloe MoretzFourteen-year-old Chloe Moretz has a slew of films in the works, including the comedy film made up of short segments, Movie 43, and the forth-coming Martin Scorcese film, Hugo Cabaret, which is set for release this November. In this pic, Moretz and Movie 43 co-star, Jimmy Bennett host an MTV show in front of the Huntington Beach restaurant Rockin' Crepes. Kanye West It was recently revealed that Kanye West attended numerous fashion shows during Paris Fashion Week uninvited – and crashed the front row. But from the looks of a recent twitpic, he was certainly embraced by fans. West tweeted a picture of himself in the crowd outside the Balmain show: "Photo from paris last week." Ellen DeGeneres Ellen DeGeneres is always very welcoming of her guests, often giving them parting gifts from her show. So when the stars of TLC's Sister Wives stopped by this past week, DeGeneres was especially considerate. DeGeneres presented Kody Brown and his four wives with embroidered outfits, and tweeted, "What kind of gift do you get for a man and his 4 wives? Easy. Snuggies." Notice the Monday, Tuesday, Wednesday, etc. labels on the Snuggies? Sofia Vergara In this twitpic, members of the Modern Family cast pose for a colorful photo op. Ed O'Neil, Julie Bowen, Ty Burrell, and Sofia Vergara, who tweeted, "Party night at Gloria's!!"
