Jessie J and Pixie Lott both oozed sophistication in satin as they stepped out to honour the late Jamal Edwards.
The Price Tag singer, 37, who is preparing to undergo her second breast cancer operation, lead the stars at the Self Belief Trust gala dinner at Dovetale in London on Wednesday.
Jessie looked sensational for the evening in a cobalt blue satin figure-hugging midi-dress, featuring spaghetti straps.
She paired the dress with an array of gold accessories, including sandal heels, a chainmail handbag, bangle cuffs and huge drop earrings.
During the evening, Jessie gave a surprise performance of a heart-moving rendition of Who You Are and got the crowd pumping with her hit Price Tag.
Meanwhile also in attendance was singer Pixie, 34, who wore a baby pink mini-dress, which featured a ribbed racer-neck top and satin skater skirt.
Pixie, who performed at the event, completed the ensemble with a pair of transparent and bejewelled slingback heels.
The event was to honour the legacy of the late music entrepreneur Jamal and raise money for his trust, which offers young people skills, opportunities, and mental health support.
Jessie was seen posing for snaps at the event with Jamal's mother Brenda and his younger sister Tamisha.
Other guests included Dame Arlene Phillips, Denise Welch, Vas J. Morgan, Tim Campbell MBE, and Big Narstie.
They were treated to live music from multi award winning artists Emeli Sandé, Pixie, Wretch 32 and West End star Alexia Khadime, with DJ sets from Laura Pradelska and acclaimed producer Jess Bays.
Prior to the event, Ed Sheeran joined Brenda Edwards and artist Lincoln Townley for an exclusive photo moment where he signed a one-of-a-kind Townley artwork, later auctioned on the night for over £100,000, while playfully sampling a 'Tingly Jam' cocktail and signature chicken dish in Jamal's honour.
Jessie's appearance comes after Jessie returned to the stage earlier this month for her first live performance since undergoing a mastectomy following her breast cancer battle.
She opened her set at BBC Radio 2 In The Park in Chelmsford, Essex to a loud applause from fans.
Appearing emotional on stage, she told the packed crowd: 'Some of you may know, some of you may not know, but I had breast cancer surgery 11 weeks ago today.
'And the last show I did, I had no idea what was gonna happen, and I'm still very much in the recovery process, but I'm definitely not ready for Babins.
'I mean, I am, but my doctors are like 'calm down, girl'. Do you know what I mean, you can take the girl out of Essex, put her back in to Essex.
'But I'm just so grateful to be here, you have no idea how grateful I am to see so many of you singing along after all these years.
'It truly feels like I'm a little kid. Still doing what I love.'
She added: 'And another special thing that's happening today is that my son is seeing me sing on stage for the first time.'
Sky, who is two years old, could be seen backstage wearing earmuffs as he waved at his mum on stage.
Jessie then moved onto her second song, her new track Living My Best Life, which she revealed was special to her.
She explained: 'Some of you may know it, some of you may not know it, but what this song's about, I was diagnosed literally two weeks before this song was released, and everyone said, 'let's stop, let's just put everything on hold' and I said, 'that's not what life's about'.'
The mum-of-one continued: 'Life is about standing in the storm but holding up your umbrella and just keep moving forward.
'And music, I don't know about you guys, but for me, music is a healer. Music is the thing that keeps me wanting to wake up in the morning and just makes me excited about life.
'And I'm grateful that I can make music that can give other people something that they might need on a hard day or a good day.
'So this song is called Living My Best Life, and that is what I'm doing every single damn day. Cause we never know when our last day will be, so soak this up, hug the people you love hard.'
