Girls' night in for Selena Gomez and Taylor Swift

Actress/singer Selena Gomez knows how to have fun without boyfriend Justin Bieber - she ate cupcakes and danced the night away with Taylor Swift during a girls' night in.

The best pals enjoyed some quality time together on Wednesday night, and Gomez shared the fun with her fans - posting an Instagram picture of the duo dancing with two friends, playing guitar and eating cupcakes.

In a post on her Facebook.com page, she wrote, "Because you need a best friend (that) sings beautifully, another best friend to dance with you and another to listen. Oh and cupcakes."
