Chris Martin and Gwyneth Paltrow will spend their wedding anniversary together.

The Coldplay frontman - who is believed to have rekindled his romance with Jennifer Lawrence - may have split from his estranged wife in March after 10 years of marriage, but they will still see one another on December 5, as well as other upcoming holidays in order to keep things as normal as possible for their two children, Apple, 10, and eight-year-old Moses.

A source said: ''Chris has said he and Gwyneth want to make things as normal as possible for the children.

''They always do something to mark their anniversary. They also intend to spend at least part of Thanksgiving together and Christmas Day.''

The 'Hunger Games' actress is said to be unhappy with the arrangement and has warned the 'Sky Full of Stars' singer he needs to prove he is serious about his marriage being over if they are to have a future together.

The source added to Grazia magazine: ''Jennifer understands that Chris needs to spend time with the kids and that he's got to be in contacts with Gwyneth.

''But she's told him that if he's serious about making things work between them, he needs to file for divorce before the end of the year and show that he's ready to move on.''
