She's maintained close relationships with her former Girls Aloud co-members since their disbandment in March 2013.
And Cheryl and her pal Nicola Roberts threw their support behind their former bandmate Kimberely Walsh as they attended Big The Musical's gala performance in aid of Make-A-Wish Foundation UK at the Dominion Theater in London on Tuesday evening.
The Love Made Me Do It hitmaker, 36, exuded confidence as she arrived at the venue in a flowy orange jumpsuit, complete with a drawstring belt to highlight her incredible physique.
Toning down her incredibly vibrant display, the songstress boosted her frame in a pair of chunky nude ankle-strap heels.
The singer upped the style ante as she complemented her appearance with a thick gold bangle, and toted her belongings in a designer chain-strap handbag.
Famed for her enviably glossy locks, Cheryl styled her golden tresses into loose waves, while her tanned complexion was accentuated with shimmery gold eyeshadow, dewy foundation and rose-tinted lipgloss.
Looking equally chic was Nicola, 33, who stood out in a shimmery black blazer, teamed with a plain white T-shirt and straight-leg denim jeans.

The auburn-haired beauty opted for a pair of patent pointed heels as her footwear choice, and carried her belongings in a patterned handbag by Christian Dior.
With her hair worn in a bouncy hairdo, the star enhanced her beauty with terracotta-colored eyeshadow, heavy strokes of matte foundation and nude lipstick.

'I'm feeling good, happy to have my girlies here, about to get my wig on, she's ready isn't she', the Strictly star said in a dressing gown as she flaunted her blonde headpiece. 'I'm nervous … the stage is massive isn't it! I guess it is called Big ', Cheryl joked.
The play is a musical adaptation of the 80s film starring Tom Hanks, which tells the story of 12-year-old Josh Baskin – a boy who is forced to tackle adulthood earlier than he thought after his wish to be 'big' is granted by a Zoltar machine.
Sound Of The Underground hitmaker Kimberely – who portrays the role of Susan Lawrence – is joined by the likes of Jay McGuinness, Matthew Kelly and Wendi Peters in the theater production. The play kicked off in the West End on September 10, with the string of performances set to come to an end on November 2.
Speaking to This Morning hosts Davina McCall and Rochelle Humes last month, she admitted that she felt 'at home' getting back into musical theater, after starring as Princess Fiona in Shrek The Musical and Jovie in Elf The Musical.
She's got company: The reality star was joined by a hunky male companion, who appeared to help her lug her monogrammed suitcase into the theater
She explained: 'I grew up doing musical theater. I felt like I got into Girls Aloud by default and it was like I went back … I feel so at home on the stage. '
'We literally lived and breathed each other so I think more time needs to have passed for anybody to get those feelings of getting us back together.'
A slew of celebrities were in attendance at the charity event, including pregnant Lydia Bright, YouTuber Saffron Barker and Love Island favorite Amy Hart. The former flight attendant, 27, caught the eye in a belted hot pink midi dress, paired with classic nude heels.
Contrasting with her bright appearance, the TV personality held onto a quilted red handbag, which worked well with her classic lipstick.
Oh baby! Pregnant Lydia Bright ensured all eyes were on her as she flashed a hint of her lean legs in a floral print tea dress, which featured a thigh-high slit

Girls Aloud, which comprised of Kimberley, Cheryl, Nadine Coyle, Sarah Harding and Nicola, was formed in 2002 on the ITV show Popstars: The Rivals. The band went on to earn 21 top 10 singles and four UK number one's before deciding to part ways in 2013.
Earlier this year, Kimberely admitted that her former band were unlikely to follow in the footsteps of the Spice Girls and form a reunion tour.
She revealed: 'There is no Girls Aloud reunion on the cards right now. The Spice Girls had a phenomenal career but it was very short, over four or five years.
