She chose not to help her on/off boyfriend Chris Brown celebrate his birthday on Friday night.

And by the looks of it Rihanna’s excuse may have been she was ‘doing her hair’ as she stepped out over the weekend with a whole new look.

The singer made sure all eyes were on her as she sat court-side at a basketball game in New York on Saturday, displaying much longer, poker straight and two-tone hair.

New look: Rihanna showed off longer straight hair as she watched a basketball game in New York on Saturday

Dressed more for a night out than for the Chicago Bulls and Brooklyn Nets game, the 25-year-old cut somewhat of a lonely figure sitting on her own.

Wearing a tiny skirt, her long legs were on show for all to see and drew attention to her strappy sandals.

Keeping it simple she teamed the skirt with a black vest which was rather low cut.

Coloured: The star had dyed her hair two tones so it was dark at the roots and gradually got lighter

However it was her very long poker straight locks, which seemed to have been dyed an extreme version of ombre with a small section of brown at the roots and long blonde sections.

On her lap she had a red clutch bag, which matched her red lipstick.

The Diamonds singer looked a little preoccupied during the game and sat with her chin resting on her hands.

Leggy: Rihanna wore a short skirt so as she sat court-side her long, slim legs could be seen

Her somewhat downcast appearance may have been down to the fact her on/off boyfriend Chris was seen partying with his ex Karrueche Tran at this birthday party on Friday in Los Angeles.

Rumours have been circulating that there may be trouble in paradise once again for the couple, which was only made worse by Karrueche’s attendance.

However sources told HollywoodLife.com that Chris and Karrueche are ‘cool friends’ and Rihanna is OK with them hanging out from time to time.

The insider added that he and the 25-year-old Stay singer are ‘into each other way too f***ing much’ to let his friendship with Karrueche come between them.

Chris, who is still on probation for violently beating Rihanna in 2009, previously revealed he would always have a soft spot for his former flame – who was recently said to have moved on with NBA star John Wall – because she supported him during the worst time in his life.

He said: ‘She was my friend through it all. It was a friendship more than a relationship. I still love her, but at the end of the day, it’s like I got love for her. She gone always be my homie!’

Shorter: On Friday Rihanna had shorter hair when she arrived at her hotel in New York

He also said he wishes ‘all the best to her. We still have a clothing line. I only want her to progress. I don’t want to stop her blessings.’

Meanwhile Chris is reportedly trying to convince Rihanna to join him at his huge birthday bash in 1 Oak nightclub in Las Vegas on Saturday after she was forced to postpone her concert in Brooklyn, New York on Sunday because the Brooklyn Nets need the venue to compete in the playoffs.
