The troubled actress - who was recent released from house arrest, served in lieu of jail time for taking a necklace from a boutique and violating the terms of probation set for her 2007 conviction for driving under The Influence (DUI) - is a huge fan of the British rockers and reached out to Chris for tickets as the pair have been "good friends" for years, according to gossip website TMZ.
Lindsay - who brought her younger sister Ali to the gig, where they enjoyed prime seats near the stage - later tweeted: "I love Coldplay!!!!!!!!!!!!!!!!! W/my sis :) (sic)"
Coldplay paid tribute to the late singer Amy Winehouse during the band's encore, where they performed a slower version of her hit 'Rehab', before singing their own song 'Fix You'.
Lindsay is not Coldplay's only famous fan. Chris' wife Gwyneth - who has two children, Apple, seven and Moses, five with her musician spouse - recently revealed she is having trouble getting hold of their new LP, which is due to be released later this year, despite her close relationship with the band.
She wrote on twitter: "Who do I have to bang to get an advance copy of the new coldplayalbum? I mean, really.(sic)"
