But, sadly, the pair did not give fans what they really wanted - a picture together!
In fact, after years of rumoured feuding, we have a feeling the pair might even have avoided each other!
Mum-of-one Nadine looked absolutely S-T-U-N-N-I-N-G when she attended the Lesbian Gay Bisexual and Transgender Awards on Friday night (24 April) at the Landmark Hotel in London.
In a plunging silk georgette column dress with hand beaded knot design, the singer oozed glamour - and narrowly avoided a wardrobe malfunction!
Meanwhile, Nicola kept it simple but elegant in a gorgeous dark green gown, which showed off her pale skin and flame red hair to full effect.
After attending the event, Nadine wrote: "I had a great time presenting tonight at the LGBT awards.
"Thank you @SamuelDougal I got to wear one of your creations! I love it! Hair/makeup by the amazing @lyndseyharr1son."
Ethereal Nicola posted the message: "A lovely evening at the LGBT Awards.. Such a pleasure to present @grahnort with his broadcaster award . Lots of inspiring stories shared."
She added: "Thank you @jpbraganza & @alisonelwin for my beautiful dress."
While both girls posed for pictures on the night, the girls were NOT spotted together - adding to more speculation of a continuing rift. AWKS!
In 2012, Nicola unfollowed her former Girls Aloud bandmate Nadine on Twitter, as did Cheryl Fernandez-Versini.
It is no secret that, despite a brief reunion in 2012 for the Children In Need charity single, Nadine is not in contact with her four bandmates Nicola, Cheryl, Sarah Harding and Kimberley Walsh.
Last year, Cheryl described Nadine as "full of s**t" for claiming she never wanted Girls Aloud to break up.
