Chris Martin showed his support for ex Dakota Johnson during a weekend Coldplay concert in Las Vegas.

A concertgoer shared footage of the moment on TikTok, which has since garnered more than a million views.

In the clip, Martin can be seen at the end of the show, thanking the huge crowd.

"Thank you, everybody! Be kind to each other!" Martin said into the mic.

He then added, "Don't forget to go see Materialists!"

The Clocks singer was referring to the new romantic comedy starring Johnson. In Materialists, which premieres this week, she plays a New York City matchmaker who becomes torn between a new potential love, played by Pedro Pascal and a messy ex, played by Chris Evans.

On 4 June, multiple sources reported that Martin and Johnson had ended their nearly eight-year relationship.

The pair, who were first romantically linked in 2017, were photographed together for the last time in May, when they stepped out in Malibu, California.

Before that, in January, the pair held hands in India, where Martin was touring with his band.

People magazine reported that Martin's ex-wife, Gwyneth Paltrow, plans to stay close to Johnson, revealing that they "developed a close friendship" over the years, and that the Goop founder "fully intends on maintaining that bond".
