The trip-hop trio recently opened for the super-group on their US shows and the young musicians took the opportunity to pick frontman Chris Martin's brain for tips to stay sane in the music industry.
Speaking at the Ivor Novello Awards in London on Thursday (22.05.14), singer Hannah Reid said: ''Coldplay really liked our album, so much that they asked us to support them in LA, which we just did, we just came back from there. That was a pretty amazing experience.
''We got a chance to hang with them a little bit, Chris told us you should respect the chemistry within your band and stressed how important that is and when you know you're getting tired take days off, which has been good advice so far.''
Hannah and her bandmates Dan Rothman and Dot Major were honoured at the prestigious ceremony with the prize for Best Song Musically and Lyrically for their track 'Strong'.
The group have enjoyed critical acclaim for their debut album 'If You Wait' and praise from their pop peers.
Vocalist Hannah is in demand to work with other artists but she insists her loyalty is with her ''boys'' in London Grammar.
When asked if she's interested in doing some collaborations, the 24-year-old singer said: ''I'm definitely not. London Grammar will always be my priority and I think that as a singer in a band you have to make that decision early on how you're going to approach that ... these two are my boys.''
'Smalls Change (Meditations Upon Ageing)' arrives in April.
The two awards have made for a great 72nd birthday present for the country music icon.
