Beyoncé and Jay-Z on the beach in St Barts

Beyoncé and Jay-Z are spending their first holiday as a family beside their baby Blue Ivy during a sun-filled stay in St Barts.

Beyoncé and Jay-Z spent yesterday on the beach where they lay on the sand and soaked up the sunshine.

The superstar couple has had very hectic schedules since the birth of their first child so appear to be making the most of their Caribbean getaway.

And they seem to be taking to parenthood like ducks to water as they make sure they have some quiet time as a couple as well as doting on their little one.

The pair both opted for black swimwear with Beyoncé, 30, sporting a one-piece and 42-year-old Jay-Z wearing swimming trunks.

They certainly seemed to be winding down as an ice bucket rested behind them which contained a bottle of wine and several bottles of water, while Jay-Z also sipped juice from a coconut.

Beyoncé was clearly feeling the heat as she then took a dip in the sea to cool off after lounging in the sunshine.

The singer kept her sunglasses on as she splashed around in shallow waters and prevented her hair from getting wet by tying it in a bun.

On Sunday the pair was seen toting little Blue Ivy as they made their way onto a waiting boat.

Beyoncé cradled her precious cargo as she made her way aboard the yacht.

The holiday comes as Beyoncé and Jay-Z are reported to have renewed their wedding vows in celebration of their fourth anniversary earlier this week.

The power couple is also understood to have exchanged new rings as they stood before celebrity guests including Oprah Winfrey, according to MediaTakeOut.com.

The website reports that the pair said “I do” again in a “moving” ceremony which happened at midnight on their wedding anniversary, April 4.
