The newly engaged songstress attended the Season 3 wrap party in Los Angeles on Thursday in a daring plunging strapless dress with a thigh high split.
The sparkling strapless top showed off her considerable cleavage while Kelly's shapely legs were on show thanks to the dramatic cut of the bottom of the gown.

winning act but Kelly Rowland ensured all eyes were on her as she
stepped out at the X Factor USA wrap party in a daring low cut, slashed
dress
The top of Kelly's dress was lit up light a Christmas tree but it was the vast amounts of flesh on show that are sure to have captured gazes.
As if that sparkly dress wasn't enough, Kelly wore a number of glitzy bangles on her wrists.
She also wore an unusual pair of black heels with a silver bar through the front.

Rowland's long Ombre hair was straightened and flowed down past her shoulders as she confidently posed on the red carpet.
She sported a huge smile despite the fact her act Jeff Gutt lost out to Simon Cowell's Alex & Sierra in Thursday's two-hour finale.

Kelly, 32, recently confirmed she is engaged to her manager Tim Witherspoon.
The former Destiny's Child star - who was first rumoured to have gotten engaged in mid November when she flaunted a diamond engagement ring during video posted to Instagram - is set to walk down the aisle with her beau of four years.

The X Factor USA judge was in Bulgaria when Tim proposed to her via Skype, she recalled in an interview on The Queen Latifah Show, which aired on Wednesday.
She gushed to her host: 'He put a ring on it!'
During the chat fest, Kelly even shared the details of the proposal.

'He asked me first on Skype and I was like, "We're so far away from each other,"' she said.
'But it was so late, I remember we were both just kinda like, honestly, just staring at each other ... and he asked me, and it was just that simple to say yes.'
The beauty, currently sporting a four carat cushion-cut diamond sparkler, feels she has finally found the right person.

The Kisses Down Low singer, who was previously engaged to NFL football player Roy Williams, is notoriously private about her love life and admitted she has kept her romance quiet for quite some time.

She said, 'It's been a while. We've kept it very, very low - for years, to be completely honest.'
While Kelly's future on X Factor is thought to be safe, co-star Demi Lovato recently quit to focus on her music career.
However, she attended the wrap party in a clinging gold dress with a black jacket and her blue hair tied back.
While his co-stars were dressed to impress, Simon looked sloppy in a white shirt and jeans. He was joined at the bash by X Factor UK winner Leona Lewis who performed on the show, host Mario Lopez and his winning contestants Alex & Sierra.
