Kate Bosworth and Michael Polish
Newly single Kate Bosworth

shared an affectionate night

They also snuck in even more kisses during the show and looked "totally adorable" together, an onlooker says. Meanwhile, lead singer Chris Martin
's wife Gwyneth Paltrow
stayed under the radar, hanging backstage during the concert.
