She went to swanky restaurant The Ivy Asia and took a bathroom selfie in the mirror, surrounded by floral interiors and a red door.
The singer wore her honey blonde hair in loose waves and posed with her leg out to the side with her head tilted.
The mother-of-two wore black trousers with a matching blazer and cheekily flashed her bra to the camera under the plunging neckline of the jacket.
Rachel looked gorgeous as she wore dark eye makeup with a pink lipstick and accessorised with a black Prada handbag and diamond earrings.
Rachel has recently announced that she is proud of her 11-year-old daughter after she landed a role in a West End show.
The songstress told MailOnline: “I’m always singing, always, and so are my kids. We’re in a very musical house and my daughter is definitely following in my footsteps.”
She continued: “I’d help her in terms of being there for advice and to guide her for sure, but it’s a very different world now, music is like a whole different industry to when I was in it.”
Rachel hasn’t released any music since 2005 but still has a passion for singing and said that her “heart was pounding” when she watched her daughter from the audience.
A source also spoke to OK! about her daughter’s success and insisted that she’s “not a pushy show mum” and instead “protected and guided” her daughter into the role of Young Eponine in Les Misérables.
They also said that Rachel is “protective” because she knows what it’s like to be “a young star” and has experienced the “pitfalls of fame”.
Despite this, the source said that performing is “all her daughter wants to do” and that she “received the gene from her mum”.
Aside from her singing career, Rachel has competed in many performing arts based shows including Strictly Come Dancing, Dancing On Ice and The X Factor New Zealand as a mentor.
She has also received many awards including NME’s Best Female Artist, Glamour’s Woman Of The Year and multiple Smash Hits Awards.
