Chris Martin is "sweeping" Jennifer Lawrence "off her feet."
The Coldplay frontman, who split from Gwyneth Paltrow in March after 10 years of marriage, has reportedly been pulling out all the stops to romance The Hunger Games actress, including writing new love songs about her, since they started dating in June.
A source told Us Weekly magazine: "He writes her songs and loves taking her to private romantic spots. Chris is sweeping Jen off her feet. That's his thing."
The 24-year-old beauty initially told pals that her romance with the 37-year-old rocker, who has daughter Apple, 10, and son Moses, eight, with Gwyneth, wasn't serious, but is becoming increasingly attracted to him since watching him perform on stage in the UK earlier this summer.
The insider said: "Jen was blown away at his London show. His music is absolutely part of the attraction. The better she gets to know him, the more she likes him."
The Magic hitmaker's friends were previously said to be thrilled he has moved on with the "carefree" actress following his split from Gwyneth, 41.
An insider said: "She's just a cool girl. She's the anti-Gwyneth. She's not so rigid, and Chris is responding to that. He's enjoying being with someone carefree. He's smiling again. Genuinely."
