The worlds of fashion, politics and rock collided in Jamaica this weekend as two high profile families had fun on the beach.

Lauren Bush-Lauren, David and Ralph Lauren joined Paul McCartney, his new bride Nancy and his children James, Stella and Beatrice for a New Year break.

Lauren, 27 - who is George W Bush's niece and George H W Bush's granddaughter - looked stunning in a navy, polka dot bikini.

The model joined her husband David, 40 - the son of fashion designer Ralph Lauren - whom she married in September.

The curvy Texan showed off her wholesome good looks as she took a dip in the Caribbean Sea with her husband.

Her hair pulled back in a ponytail and her face make-up free, she seemed relaxed.

The couple holidayed with fashion designer Ralph, who unveiled an impressive six-pack for a 72-year-old man.

The American seemed very comfortable with her stepchildren that were present, James, 34 and fashion designer Stella, 40, who are from his marriage to his late wife Linda.

His youngest daughter, Beatrice, eight, was also present. Her mother is the singer's ex-wife Heather McCartney.

At one point James didn't seem uncomfortable when his father scooped his new bride into his arms and kissed her.

The couple were also spotted walking hand in hand and with Beatrice.

The two sets of newlyweds married within a month of each other.

Lauren and David walked down the aisle at Ralph's Colorado ranch in September.

The bride's dress was designed by her father-in-law.

Meanwhile, Paul and Nancy married in London in October.

Lady McCartney's dress was designed by her future step-daughter, Stella.
