Ed Sheeran will headline Glastonbury 2017.

The 'Thinking Out Loud' hitmaker - who has been on hiatus for the last year - will reportedly make one of his musical dreams come true when he tops the bill at the world-famous musical festival in Worthy Farm, Somerset, next June.

And Ed's signing has delighted the event's organisers, Michael and Emily Eavis.

A source told The Sun newspaper: ''Michael is delighted to get Ed signed up.

''It's going to be a huge moment for the festival having him up there marking his comeback in front of a giant crowd.

''Ed's always said headlining Glastonbury has been a big ambition of his.

''Topping his three sold-out Wembley Stadium shows last year will be tough, but this is as big as it gets.''

Ed will join previously-confirmed headliners Radiohead at the event, while Foo Fighters - who were forced to pull out of the 2015 festival after frontman Dave Grohl broke his leg - are expected to be the final headliners.

The news comes a few days after the 25-year-old singer returned to Instagram and Twitter, exactly a year after announcing he was taking a break from social media.

Posting the same photo on both social media outlets, the 'Sing' hitmaker uploaded a plain light blue background with no caption, before also changing his profile picture on each site to the same image.

The 'Sing' hitmaker's last post detailed how he was going to ''travel the world'' before promising his fans he would be back soon to work on his third studio album.

He wrote on the photo: ''Hello all. I'm taking a break from my phone, emails and all social media for a while, I've had such an amazing ride over the last 5 years but I find myself seeing the world through a screen and not my eyes so I'm taking this opportunity of me not having to be anywhere or do anything to travel the world and see everything I've missed.

''To my family and friends, if you love me you will understand me buggering off for a bit, to my fans, the 3rd album is on its way and is the best thing I have made thus far.

''See you all next autumn, and thank you for being amazing. Ed. x (sic)''
