Actress Gwyneth Paltrow celebrated this year's Valentine's Day with her estranged husband Chris Martin.

The 42-year-old and the Coldplay frontman, who separated last year after ten years of marriage, were seen walking together on the beach in Malibu along with their children --son Moses and daughter Apple, Saturday, reports dailymail.co.uk.

In some of the photographs, the couple is seen walking arm in arm along the sand together in what appeared an epitome of a happy family scene. This has prompted rumours of a reconciliation.

The `Iron Man` actress features in the photograph wearing dark blue capri pants with a black tank top and she hid her eyes behind dark glasses.

Meanwhile, Martin, 37, co-ordinated his look with that of his estranged wife with knee length blue shorts, light blue T-shirt and a baseball cap with a smiley face logo.

The couple announced they were separating almost a year ago in March 2014, but neither of them has filed for divorce.
