Superstar couple Beyoncé and Jay-Z have marked another first in their daughter's life by taking Blue Ivy Carter on her first vacation.

The singer and her rapper husband headed to the sun-soaked Caribbean island of St Bart's with their three-month-old over the Easter weekend, just days after celebrating their fourth wedding anniversary.

Beyoncé, 30, and 42-year-old Jay-Z were spotted on the celeb-friendly island with their daughter, as well as spending some quality time alone as a couple.

The Carters, who reportedly renewed their wedding vows earlier this month, were seen strolling hand in hand and also relaxing on the beach sipping champagne.

With her hair tied back in a ponytail, a fresh-faced Beyoncé and her other half also found time to catch up with family and friends on a yacht around Nikki Beach.

Guests aboard the luxury liner included Beyoncé's mother, Tina Knowles, and her cousin, Angie Beyince.

The Single Ladies singer used the holiday as an opportunity to show off her post-baby curves and wore outfits that displayed her toned legs.
