Justin Bieber and Rihanna get cosy on courtside seats at NBA All-Star game

Life couldn't get much better for superstar Justin Bieber and this weekend proved no different as he sat courtside during an NBA All-Star basketball game next to Rihanna.

Having the best seats in the house meant the 16-year-old was able to throw the ball around with the players and sit side by side with Rihanna when she wasn't performing at the event.

It wasn't just an all-star game at Staples Center in Los Angeles, but it also marked the Rude Boy singer's 23rd birthday, who put on a raunchy show at half time.

After the R&B star cavorted on stage in a skimpy outfit though, she changed back into a more appropriate ensemble of trousers and a knit top to hang out with Bieber.

The pair giggled together as Justin showed Rihanna something funny on his phone and ate popco as they enjoyed the game.

The stars were watching the final event of the All-Star competition between the Easte and Weste Conference, with the West team winning with a score of 148-143.

Just a couple of days earlier, Bieber had also played as part of the West team, which was coached by Magic Johnshon, and the pint-sized singer managed to be named the Most Valuable Player.
