Im not that familiar with Pornstars either. But that isnt Nikki Nova. I know LPZip sells that package under the name "Nikki" but not the name "Nikki Nova" which they also carry several sets of. I have a gallery of Isabella which I purchased from Zipcontent, I assume she also used that name.
Look familiar;
