Beyoncé Knowles loved "pigging out" on Valentine's Day.

The 'Crazy in Love' singer - whose is rumored to be engaged to rapper Jay-Z - wanted to gorge on calorific treats on the most romantic day of the year after spending months dieting for her duet with Tina Turner at Sunday's Grammy Awards.

When asked how she would be spending Valentine's Day, Beyoncé said: "To get into my outfit I had to work hard and now it's over I just want to pig out. Now the awards are over I can eat whatever I want. Chocolate, sweets, carbs, everything!"

The former Destiny's Child star, famed for her curvaceous figure, squeezed into a tiny silver dress for her performance with the legendary singer at the prestigious event.

Jay-Z revealed he was planning a romantic surprise for Beyoncé.

The producer told US TV show 'Extra': "I'm very romantic and very suave. I'm going to do something really great for her but only she'll know about it!"
