Kelly Rowland looked calm and collected while attending the birthFUND Brunch in Los Angeles on Thursday afternoon.
The star, 43, looked beautiful in champagne colored strapless jumpsuit with sparkling details along the torso.
The Destiny's Child singer paired the elegant silky one-piece with several necklaces, adding black slip-on heels and small framed sunglasses.
Kelly, who grinned ear to ear, styled her chin-grazing platinum locks sleek with a deep side part.
Her sighting at the event comes two weeks after she appeared to scold a security guard while walking the red carpet at Cannes.

Kelly was attending the premiere of the French film Marcello Mio, looking incredible in a strapless red dress with a statement diamond necklace.
The star appeared to have a verbal dispute with a member of the security.
The female security guard held up her arm to guide Kelly into the venue - and Kelly appeared furious, holding up her finger in the air in front of the crowd in attendance.
The security guard then appeared to frantically respond to the star, who turned back to her to continue her tirade while still walking up the stairs.
A lip-reading expert revealed what Kelly really said during the heated interaction with the French woman.
Jacqui Press told MailOnline that after the security guard appeared to step on her dress, she apologized and Kelly said: 'It's OK.'
However, the security guard then said something else, causing Kelly's change in mood, as she responded: 'Don't talk to me like that.'
She continued to usher Kelly up the stairs and she turned around and repeated the phrase several times.
A male security guard came down to ask what was being said as the female security guard was still using her hands to move Kelly along the steps.
Kelly finally turned around on the top step and added: 'You still don't talk to me like that!'

Kelly spoke out about the dispute while walking the red carpet soon after:'The woman knows what happened. I know what happened. And, I have a boundary. And I stand by those boundaries and that is it.'
'There were other women who attended that carpet, who did not quite look like me, and they didn’t get scolded or pushed off or told to get off,' she added.
It was claimed that the tiff came about because staff members were 'being aggressive' and Kelly had 'had it' with them.
'The people who are assigned to helping stars walk the red carpet were being aggressive and Kelly was trying to ignore it,' an insider told DailyMail.com.
'By the time she got to the last woman she had had it because she scolded Kelly and told her to move when she was trying to wave to fans and help the paparazzi get their shot,' they added.
The source also revealed: 'She doesn't care if she comes across like a diva if she knows that she is advocating for herself. She isn't fake and wanted to set a clear boundary.'
It comes just weeks after Kelly walked out of an appearance on the Today show in February, though the reason for this has been disputed.

It had been claimed that Kelly skipped out on co-hosting the rest of the Today show alongside anchor Hoda Kotb because she was dissatisfied with her dressing room, forcing Rita Ora to step in at the last minute.
However sources have since claimed that Kelly had actually walked off the show due to 'disrespect' shown to her by Hoda's co-host Savannah Guthrie who 'aggressively' questioned her about Beyoncé - rather than ask the singer about what she was there to promote - her new film Mea Culpa.
