Celebrities love to post pictures of "selfies" (the nickname of self-portraits) on their social media accounts and Enstars has gathered some of the top Twitter and Instagram photos of the week.

Among the photos that were posted stood out those from the 55th annual Grammy Awards held in Los Angeles on Sunday, Feb. 10. Many of the musical guests, performers and winners posted photos during, before and after the awards ceremony.

Taylor Swift posted an image of herself holding the Grammy she won that night. Jessica Biel, who sat front row with Beyonce and their spouses at the Grammys shared a photo that showed off her new haircut with bangs and megawatt smile. The actress attended the event because her husband, Justin Timberlake performed onstage with Jay-Z at the Grammy Awards. They performed Timberlake's latest track Suit & Tie, the first single from his highly anticipated album. The 20/20 Experience is set to release in March.

Selena Gomez went to the Warner Music Group InStyle 2013 Grammy after party at the Chateau Marmont in West Hollywood after the Grammys. The 20-year-old star posted a pic of herself flaunting her sexy side in a cropped bustier top

"He's bringing sexy back...And it's about time!! @jtimberlake killed it! Gomez captioned the split photo that featured an image of her, a friend and a snap she took of Justin Timberlake on stage.

The next day, The Game ran into country singer Carrie Underwood. The west Coast rapper took a picture with the blonde beauty and posted it on his Instagram account.

"Ran into Carrie Underwood at Starbucks... Real kool chick.. Had to put her down with 60daysoffitness," he wrote on Feb. 11

Kim Kardashian, who is four months pregnant, has been posting old photographs of herself since she put on the inevitable weight gain. Her latest offering showed a very slim Kim in a crop bustier top and lurex pencil skirt with straight hair swept to one side.

"Straight hair don't care"  she tweeted on Feb. 13.

Rihanna tweeted a photo of a massive marijuana plant on Valentine's Day.

"Roses are green! Somebody knows how to make me happy," she wrote with the photo.

It's not known whether Rihanna's secret admirer was Chris Brown because she reportedly spent the holiday solo by attending a Ne-Yo concert in Los Angeles.

E! reality star Nicole "Coco" Austin shared a picture of her tiny dog giving her some extra love on Valentine's Day- the image on Whosay showed her Chihuahua hugging her ankle.
