Dakota Johnson and Chris Martin have further fuelled speculation they are dating.

The 'Fifty Shades Freed' actress and the 40-year-old musician have been the centre of relationship rumours for months, and whilst neither pair have confirmed or denied the reports, they added fuel to the fire on Friday (12.01.18) when they stepped out for a romantic dinner date.

The couple were spotted enjoying a bite to eat in Malibu, and eyewitnesses claimed the 28-year-old actress and the Coldplay frontman ''seemed very happy'' during their date.

A source told People magazine: ''Chris and Dakota arrived together in Chris' car. They met up with friends and had a fun night. They both seemed very happy. They were flirty, and also left the restaurant together.''

The stars first sparked relationship rumours in October last year after they were spotted on a sushi date night, and set tongues wagging again in December when they were pictured strolling out of the French capital's Charles de Gaulle airport on Tuesday surrounded by security.

But the pair's romantic getaway didn't completely confirm their relationship, as although they arrived at the destination together, they reportedly kept their distance as they made their way through departures.

It has been reported the duo have become ''very comfortable'' with one another over recent months, and the 'Yellow' singer has even consulted the beauty on his music.

Speaking previously about their love life, a source said: ''Dakota and Chris are definitely dating.

''They've got to know each other really well and are very comfortable from one another. Chris sends Dakota his music to get her opinion. It's more than just a fling.''
