After reports that Selena Gomez has allegedly gone for breast enhancement surgery and showed off her new assets in a clinging braless sheer top, the Texan beauty has now suffered a nip slip. Selena posted a picture of herself enjoying a night out with her friends where she is so busy posing for the perfect shot that she is completely unaware of the wardrobe malfunction happening to her.

The singer's black cleavage-revealing lace top gets pulled down a bit as she stretches her body and as a result one of her nipples is exposed to quite an extent. Check out the picture here. Selenators were quick to realize Selena's accidental nip slip and have immensely liked and commented heavily on her black and white picture.

However, many online publications are surprised at the fact that the "Come and Get It" singer has posted her nip slip picture on her own Instagram profile. Selena's daring act has led to speculations that she posted the picture without her knowledge or did it to grab media attention.

"Maybe she didn't notice? That or she really doesn't mind at all," asks Mirror.

"And we guess she didn't notice that it seems one of her girls had gotten loose!" writes Perez Hilton.

While Selena Gomez has been busy partying with her friends and pouting in most of her Instagram pictures, Justin Bieber is happily enjoying his time with new pal Yovanna Ventura. The 18-year-old model and fitness trainer calls Bieber the "sweetest guy ever" in her Instagram pictures. The two are seen posing together in several of her selfies.

Apart from Yovanna, Justin was also seen having a good time with another friend Chantel Jeffries. Chantel is the same girl who was with Justin when he got arrested for DUI and alleged drag racing in Miami, earlier this year.

However, Justin's slew of new girlfriends seems to have no negative effect on Selena Gomez who has been enjoying her own time with friends. The singer has however posted several cryptic messages on her Instagram account. "The moment you compare yourself [to other woman], it weakens you, and I am not here for that. Once you know the reality [and] claim your space, your life becomes easier," read one of the messages.
