The performer grinned from ear to ear at the basketball game as she donned a colourful head piece in support of her team.

The Empire State Of Mind hitmaker kept it casual in a white and black shiny jacket which she paired with black jeans and knee high black boots.

On her head was a colourful paper head piece made up of flowers, hearts and flames with the team name ‘Liberty’ stuck on the front.

The singer watched as New York Liberty were crowned victorious in the WBNA playoff semifinals against Connecticut Sun.

In one snap, Alicia looked over the moon as she raised her hand in the air to celebrate the score.

The star completed her look with a pair of square-framed sunglasses and chunky gold hoops.

She was joined by co-owner of New York Liberty and businesswoman Clara Wu who looked stylish in a leopard print wrap dress.

Clearly friends, the pair held hands as they smiled for a sweet snap together during the game.

Alicia was also seated next to American rapper and singer Red who true to her name was easily identifiable with her bright red hair, red glasses and red teeth grill.

Documenting the game over on her Instagram Story, Alicia enjoyed herself as she was given full reign of the T-shirt.

The star also got a snap with the basketball team as they all grouped together after the match as she captioned the post ‘@nyliberty 4 the win’.
