Gwyneth Paltrow made a surprise appearance in a new Astronomer ad following a viral Coldplay concert scandal involving the company’s CEO and HR chief.

"Astronomer has gotten a lot of questions over the last few days," the actress - and Chris Martin's ex - says in the ad.

A tech company whose CEO resigned after being caught on video at a Coldplay concert embracing another employee has hired Gwyneth Paltrow as a temporary spokesperson.
