Robert Pattinson and FKA twigs enjoyed a date night at the Annual GO Campaign Gala.
The 'Twilight' star and the 'Two Weeks' hitmaker were joined on their romantic night out with 'Dark Horse' singer Katy Perry and even managed to secure themselves the top bid on a holiday.
A source told Us Weekly magazine: "He was transfixed and totally smitten [with FKA twigs]."
The 27-year-old singer - whose real name is Tahliah Barnett - later took to the stage, where she wowed the crowd with a fantastic performance.
Meanwhile, the 28-year-old actor is said to be very much in love with his fiancée.
A source said: "They looked very much in love and were very comfortable with each other and around the other guests as well. They spent the whole night together enjoying the food and the cocktails but were quite low-key. They just had a good time and enjoyed the party like everyone else.
"They are a really cute couple. They were cozied up in one of the side booths watching Grace Jones perform, keeping a low profile and chatting away among a group of friends. Then they stood up and danced for a bit on the banquette seats. So they were kind of dancing on the tables really."
