Chris Martin introduces Jennifer Lawrence to his friends

Los Angeles - Chris Martin has introduced Jennifer Lawrence to his friends.

The 37-year-old Coldplay frontman reportedly invited The Hunger Games actress to a dinner at Chateau Marmont in West Hollywood with his pals.

A source told E! News: "They seem very comfortable in each other's company - and happy!

"It doesn't seem like it's a new relationship. They seem super affectionate and at ease with each other."

Chris has reportedly been dating the 24-year-old actress since June and the couple was the "centre of attention" at the restaurant.

The source added: "She is very gregarious and confident ... They seem super cute together."

Jennifer - who was seen holding hands with Chris throughout the night - is the first person the singer has romanced since "consciously uncoupling" from Gwyneth Paltrow earlier this year after 10 years of marriage.

Meanwhile, it has been revealed that the A Sky Full Of Stars hitmaker has been trying his best to win over Jennifer by writing love songs for her.

The insider said: "He writes her songs and loves taking her to private romantic spots. Chris is sweeping Jen off her feet. That's his thing."
