Singer Chris Martin is reportedly planning to introduce his kids to his rumoured girlfriend and actress Jennifer Lawrence.

The 37-year-old singer has two kids - Apple, 10, and Moses, eight, with estranged wife Gwyneth Paltrow, who is not too pleased about the idea, reports radaronline.com.

"Gwyneth was absolutely stunned when Chris told her he wants to introduce the kids to Jennifer. It won't be happening right away. Chris wants to make sure this relationship isn't going to just fizzle out before taking such a big step," said a source.

"He sees this relationship going the distance. This has been a huge blow to Gwyn's ego because she has always bragged that she has Chris wrapped around her finger," the source added.

The rumoured couple have been dating since June.
