Glen Campbell's daughter is ''heartbroken'' following her father's passing.

Ashley Campbell took to her Twitter account to post a heartfelt tribute to the country music legend, who died on Tuesday (08.08.17) aged 81 after a ''long and courageous battle'' against Alzheimer's disease, in which she admitted he was ''everything I ever will be''.

Attached to a picture of her hand holding her father's, the singer wrote: ''Heartbroken. I owe him everything I am, and everything I ever will be. He will be remembered so well and with so much love. (sic)''

Several stars have paid tribute to the 'Rhinestone Cowboy' hitmaker - who was also behind songs 'Wichita Lineman' and 'By The Time I Get To Phoenix' - including his pal Brian Wilson.

He wrote on Twitter: ''I'm very broken up to hear about my friend Glen Campbell. An incredible musician and an even better person. I'm at a loss. Love & Mercy. (sic)''

Country music star Blake Shelton also took to social media to reveal he was praying for Glen's family following his death.

He tweeted: ''Extremely sad to hear that Glen Campbell has passed away. My prayers and thoughts go out to him and his family.''
