Leigh-Anne and footballer Jordan left The May Fair Hotel on Tuesday night (24 September) and headed to popular celeb nightclub Mahiki as they raised a toast to Little Mix's very first cosmetic line for make-up brand, Collection.
Leigh-Anne looked gorgeous in a silk patterned jumpsuit, which she teamed with black peep-toe heels. Beaming from ear-to-ear, the singer kept her hair slicked back into a ponytail and rocked bright red lipstick.
Bandmates, Jesy Nelson and the newly engaged Perrie Edwards were also pictured looking glamorous as they left the hotel.
Perrie, who wowed in a striking red jumpsuit and white block heels, made sure to flash her sparkling engagement ring!
The blonde, who is engaged to One Direction star Zayn Malik, clutched a goody bag from her own make up range but the ring was her perfect accessory on the night. Like Leigh-Anne, Perrie kept her hair slicked back and rocked smoky eye make up.
Jesy showed off her curves in a red slinky high-neck dress, with cut out detail to the shoulder and arms. She teamed her dress with black heeled sandals.
Meanwhile, bandmate Jade Thirlwall celebrated the launch by dining out with her mum Norma and close friends. She said: "Been to a posh resteraunt to celebrate launch of our new @CollectionLove range with @normathirlwall @anna_sophieb @hollyyrobinson2."
Taking to Twitter last night, Leigh-Anne added: "Feeling wavy lol but had such an amazing day! Can't believe we have our own make up range with collection! It's every girls dream! L x."
