Taylor Swift threw a party for Ed Sheeran over the weekend, to celebrate his relationship.

The Shake It Off hitmaker showed love is all around as she marked her best friend Abigail's engagement and the You Need Me, I Don't Need You singer's one year anniversary with Cherry Seaborn.

Abigail wrote on Instagram: "When there's literally so much love around your only option is to make a room for all of your love banners & sing love songs to each other. @taylorswift we LOVE you! Kudos to @teddysphotos [Ed Sheeran] for the photobomb of the year. (sic)"

Ed can be see in the background of a social media snap on Taylor's Instagram snogging his other half, while the singer poses with Abi and her man.

We imagine the superstar's new boyfriend Tom Hiddleston was allowed to take a five minute breather.

Ed and Cherry have known each other for years, and we hear things are getting very serious for the couple. Could there be wedding bells soon?

Meanwhile, Taylor previously gushed about Ed for inspiring her with his "drive and passion".

She shared: "Ed and I had been on tour together all year on the Red Tour and we saw each other almost every day.

"I lived for the moments he would burst into my dressing room with a new song to play me. It happened so often that it became normal, and I don't think he ever knew how much it meant to me that he wanted me to hear his songs first.

"I don't think he ever knew how inspired I was by his drive and passion to constantly create new art ... You deserve everything you have, and everything you will continue to achieve, Ed."

And Taylor also recalled the first time she heard Ed's track 'Thinking Out Loud' while out shopping in London.

She added: "Looking back on the highlights of my life, there's a moment I'll never forget from a day in London about two years ago. I was in town to play the O2 and I was out shopping on my day off.

"My friend Ed Sheeran met up with me in this little shop where I was buying ballet shoes. He walks in and says, 'You have to hear this new song. I think it's the best one I've ever written.'

"And then, as usual, he pulls out his phone and gives me headphones. I sat there on a bench in that store and heard 'Thinking Out Loud' for the first time, as little kids were picking out tutus and leotards next to us.

"Little did we know it would go on to be first dance song at countless weddings all over the world, become Ed's biggest hit, and eventually go on to win him Song of the Year at the 2016 Grammys."
