The media is abuzz with speculations that Selena Gomez and Justin Bieber have broken-up as they have not been seen spending quality time together recently. It maybe because both of them lead very busy and happening lives.

Selena, Thursday, tweeted a picture of her with her handsome co-star, saying that they have been burning the midnight oil, while working on the scenes for "Wizards of Waverly Place". "Shooting at 2 am and this is where me and Gregg end up..."

In the photo,  Selena is lying on her back besides her co-star, Gregg Sulkin, with their legs stretched out and resting against a wall.

Lately, many celebrities have reportedly broken up owing to busy lives. For instance, Leonardo DiCaprio and his girlfriend, Victoria's Secret supermodel Erin Heatherton, went their separate ways after over a year of dating each other, blaming their "crazy schedules."

The busy lives of young celebrities and the time they spend apart seem to eventually take a toll on their love lives.

According to reports, Selena is currently in Los Angeles for her forthcoming movie, while Justin is busy filming s segment alongside supermodels for "Victoria's Secret Fashion Show 2012."
