Sir Elton John and David Furnish welcomed celebrity guests to their annual legendary White Tie and Tiara Ball on Thursday night in London.
The star-studded guestlist included A-listers Uma Thurman, Elizabeth Hurley, Samantha Barks and boyfriend David Gandy, Matthew Morrison and Chris Martin.
A highlight of the evening was when hosts Elton and David announced Glee star Matthew Morrison's engagement to his model girlfriend of two years, Renee Puente.

Elton and Coldplay singer Chris Martin then took to the stage to serenade the happy couple with a duet of Your Song which fitted neatly with the theme of the night, "Love".
Matthew looked dapper as usual in a tailored suit and bow tie, while Renee kept her look classic opting for a dark, embroidered gown that lent all attention to her diamond engagement ring.
Uma followed suit and looked classically elegant in a black floor-length gown that flaunted her incredible figure. Elizabeth Hurley, a close friend of Elton, dazzled in a berry-coloured gown with a high slit that revealed her toned legs.
Samantha Barks and her model boyfriend David Gandy turned heads as they arrived looking just as glamorous. The Les Miserables actress stole the limelight with her white silk, plunging gown that showed off her ruby red necklace.
Other celebrities who attended included Eva Herzigova, Natalie Imbruglia, Freida Pinto, Jerry Hall.
Guests enjoyed a cocktail reception in the beautiful gardens before moving on to dinner in a marquee, and happily danced the night away around a heart-shaped bar.
The Old Windsor estate was decked out with red velvet beating hearts displays, adorned with unique Chopard jewels and watches.
The newly-engaged couple, Matthew and Renee, were all smiles and fit in perfectly with the loving theme.
"Renee is definitely the one," said Matthew, speaking previously in an exclusive interview with HELLO! Online.
"When I first met her, it was definitely one of those things. She walked into the room and took my breath away, she's gorgeous."
Matthew, 34, and Renee, 26, are currently in England to promote the Glee actor's new album Where It All Began. The charismatic actor is clearly set on Renee and is said to be completely loved-up with his fiancé.
"It's funny," he said. "You date your whole life and you definitely know what you want and what you don't want from going through the ringer."
The couple are often spotted around Los Angeles but try and keep a low-profile. "I'm kind of a homebody," he said. "We love cooking together. We're also really into horses.
"I think there is nothing more romantic than going on a horseback ride with the person you love and just enjoying the beautiful animals and scenery."
