Sometimes a night out with the girls is just the thing. Even if you are almost old enough to be their mother. Mail Online reported.

Spending the evening with her younger friend Gwyneth Paltrow certainly seemed to be doing Madonna the world of good.

The 50-year-old singer smiled and laughed as she chatted with Miss Paltrow at a dinner in New York.

With Madonna now dating a 22-year-old model called Jesus after divorcing Guy Ritchie, there was, of course, plenty to talk about.

Her younger man has given up his life in Brazil to move in with her in Manhattan.

She is said to be insisting he follows her daily macrobiotic diet with no sugary treats, dairy products and processed food.

Miss Paltrow, 36, glowed in a strapless black gown and peeptoe heels. Madonna looked a little less sleek with a curlier hairstyle than usual - and a rare glass of wine.

The pair, who have been friends for ten years, were at a dinner party after a screening of the fashion documentary Valentino: The Last Emperor.

After the film was shown at the Museum of Modern Art, a host of stars, including the fashion designer himself, went on to The Oak Room in the city's Algonquin Hotel.

Madonna and Miss Paltrow sat next to one another on the leather seats and chatted animatedly throughout the meal. They wore matching red Kabbalah bracelets on their left wrists.

Miss Paltrow has never publicly spoken about following the faith, but Madonna is understood to have introduced the actress to the branch of Jewish mysticism.

Gwyneth also once followed a strict macrobiotic diet, but ditched it when she became pregnant with her son Moses.

Kabbalah texts claim the red bracelets protect wearers from negative forces.

Miss Paltrow, who is married to Coldplay singer Chris Martin, also shares Madonna's love of yoga and tough exercise regimes. They even have the same fitness trainer.
