Nikki, who plays Maxine Minniver in the Channel 4 soap, oozed sophistication in a wide-leg purple jumpsuit with a plunging neckline.
Keeping her hair slicked back, the actress flashed a radiant smile as she posed for photographers outside The Grosvenor House Hotel.
Nikki also joined her co-star Jennifer Metcalfe for a photo, but it looks like the two were enjoying a little dance in front of photographers!
The friends were pictured holding onto each other's hands, and they appeared to be in hysterics as they shared a private joke outside the venue.
In Hollyoaks, viewers recently saw Maxine seek comfort in abusive ex-partne Patrick Blake after the doctors revealed that their daughter Minnie will need an operation.
Nikki joined Hollyoaks as Maxine in November 2012. She is also well-known for her role as Candice Stowe in Coronation Street from 1999 to 2005.
