Taylor Swift skipped out on the 2019 Grammy Awards in Los Angeles to attend the BAFTAs in London with her boyfriend, British actor Joe Alwyn.

Swift, who was nominated for best pop vocal album at the Grammys for Reputation but lost out to Ariana Grande's Sweetener, decided to support The Favourite star Alwyn at the BAFTAs, where it took home seven awards, including Best Film.

The popstar posted a picture of herself wearing a baby blue Stella McCartney gown to Instagram and wrote: "AHHHHH @thefavouritemovie just won 7 @bafta awards !!! Bout to go give some high fives - thanks @stellamccartney for this dressss 😆"

Attendees at the BAFTAs registered their excitement at Swift's appearance.

Writer Safraz Manzoor tweeted: "Trying to work out if I have the courage to say hello to Taylor Swift."

The Sun's Dan Wooton posted a series of photos of Swift and Alwyn embracing at the BAFTAs dinner.

The couple were later photographed leaving the British Vogue after-party hand in hand.
