Alicia Keys

No need for handwritten cards when you’ve got Twitter! Grammy Award-winning singer Alicia Keys professed her love for her husband, music producer Swizz Beatz, through social media in honor of their third wedding anniversary. “Happy anniversary! The love of my life!” she tweeted. Of course, Beatz returned the love, tweeting to Keys, “Cheers to My Queen and 100 plus more years!”

Nick Jonas

Someone’s been hitting the gym! Nick Jonas posted a rare revealing selfie this week, tweeting, “I never do this but…Healthy living and fitness update. Post workout picture. #diabeticinshape. #2.0.” The singer is now on tour with brothers Kevin and Joe in support of their upcoming album, V.

Chris Rock

Chris Rock had fun with actress Gabrielle Union on the set of his new movie. “Me and gab on the set,” he captioned this photo on his WhoSay page. The actor’s most recent film, Grown Ups 2, opened at No. 2 at the box office last month despite negative reviews from critics.

Eliza Dushku

She’s a recycler! “One person’s trash is another person’s #score! @rickafox lol #HeMadeMeLeaveThem #iwentback #thrifty,” tweeted Eliza Dushku at her boyfriend, former NBA player Rick Fox. She also tweeted her sadness at the death of actress Eileen Brennan, who died from bladder cancer at the age of 80.

Carly Rae Jepsen

Call Me Maybe” singer Carly Rae Jepsen embraced her inner child with a pair of Minnie Mouse ears on a trip to Disney. “Guess where I spent yesterday? #Disneyland,” she tweeted. The Canadian songstress, who goes on tour later this month, earned some laughs in July with an awful first pitch at a professional baseball game.

Barack Obama

You’re never too important to have fun! Barack Obama took a break from his presidential duties this week to play a game with a young White House visitor. “Peek-a-boo,” he tweeted along with this picture of himself amusing a little girl.

Jay Leno and Kristen Chenoweth

Actress and singer Kristen Chenoweth didn’t go alone to her appearance on The Tonight Show with Jay Leno. “@KChenoweth brought a special (and fluffy) guest backstage with her tonight!” tweeted Leno. During the show, Chenoweth kept audiences laughing with her parody performance of “Popular,” in which she offered advice to Anthony Weiner.

Adam Shankman

Director Adam Shankman tweeted this picture of himself with actor Vin Diesel with the caption “Get ready! We’re comin at you again! #TheMachine.” The two men are reuniting for the action comedy after working together on 2005’s The Pacifier. Shankman, who also directed several episodes of Glee, was a close friend of Cory Monteith’s and said he spoke to the actor only hours before his death last month.

Alessandra Ambrosio

If only winter was always this warm! “This is what winter looks like in Brazil,” tweeted Alessandra Ambrosio in this beach selfie. The Victoria’s Secret supermodel is vacationing in her native country with her fiancé and two children.

Moby

Singer-songwriter Moby posted this sweet shot of himself and a baby girl. “Playing banjo for Mona,” he tweeted. He is set to release his 11th studio album, Innocents, in October.

Ramona Singer

Taking advantage of the warm weather, Real Housewives star Ramona Singer tweeted, “Getting some sun! Back to work tomorrow so better enjoy it now!” It seems as if Singer is having a much better summer than New Jersey housewife Teresa Giudice, who appeared in court this week with her husband, Joe, to battle a slew of legal charges.
