Dakota Johnson and Chris Martin fueled dating rumors on Tuesday when they attended Stella McCartney‘s Autumn 2018 Collection show in LA.

DAKOTA JOHNSON & CHRIS MARTIN COZY UP AT FASHION SHOW

The pair entered through a private entrance to skip the red carpet, but once inside they showed off their relationship with PDA. “They walked in holding hands and Dakota was not letting go,” a source told People. “She was super into the PDA. When Chris let go of her hand, she slipped her arm through his.”

The Fifty Shades star, 28, was previously linked to model and musician Matthew Hitt, while Martin had a public divorce from ex Gwyneth Paltrow in 2016. The pair share two children – Apple, 13, and Moses, 11.

At the fashion show, Johnson donned a sparkly dress and high ponytail while the Coldplay frontman wore a simple shirt and pants with a baseball cap and scarf. “They had their arms around each other during Bruno Mars song ‘Finesse.’ Chris bobbed his head around as she leaned into him,” the onlooker added.

Johnson and Martin have sparked gossip about the beginnings of a relationship since back in October when they were spotted on a sushi date. In November, she was seen in fan photographs at a Coldplay concert in Argentina.
