The actress - who plays Maxine in the Channel 4 soap - was accompanied by businessman Greg Whitehurst at the glitzy awards ceremony on Saturday, 16 May.
Their relationship made headlines over the weekend after it emerged Greg is separated from his wife but still married, and that Nikki had attended their wedding.
In a statement to MailOnline, the actress explained: "'I have known Greg and his family for many years. Greg's marriage ended in January, it was a very difficult time for him during which all of his friends and family supported him."
She added: "We have started recently dating and it's early days, so we are not rushing into anything but are both enjoying each other's company."
Nikki brought Greg as her date to the wedding of co-star Kieron Richardson recently.
