Rihanna gets flirty with a male companion at the basketball game

On Saturday night her boyfriend was spotted partying the night away with a mystery blonde lady.

And on Sunday, Rihanna appeared to be getting her own back as she spent some time with a male friend at a sports game.

The 25-year-old singer was pictured with a friend in courtside seats at the Los Angeles Clippers vs Los Angeles Lakers basketball game.

She didn’t appear to let the news of her 23-year-old beau’s flirty night out affect her, smiling while the man chatted to her.

Whether it is a romantic interest of hers or not, the star certainly was determined to show she was having a good time as she settled into the event.

She leaned in and laughed as her company spoke to her while trying to keep her eyes on the action.

But the brown-haired beauty couldn’t help but shift her attention to the fellow guest in between munching on a large bucket of popco.

Rihanna didn’t even seem to notice that Black Eyed Peas frontman Will.i.am was just one row behind her and the producer had to tap her on the shoulder to get her attention.

The performer certainly stood out in her eye-catching get-up.

She donned a backwards baseball cap, with black vest and jogging bottoms, which she paired with high heels and dark lipstick.

Her on-and-off partner Chris was making an appearance at Hollywood’s Playhouse Nightclub the evening before and seemed to have no regard for Rihanna - who he was harping on about earlier in the week – as he handed the female a bottle of champagne.

In a radio interview with Power 105.1, he said: ‘I'm just a regular guy so I be thinking, man I hope nobody's hitting that. 

'But you can't be the jealous boyfriend, I can't be calling her constantly asking what she's doing so I just gotta put that trust out there and hope nothing happens.’
