I don't know but I do have a suggestion you can use to find out for yourself.
Load your game (or Start New Game) but choose a different household to play. A household with only one Sim is probably best. Use cheats, if necessary, to turn the Sim into a vampire and gain enough celebrity to host a meet and greet. Then, give it a try. You can Exit to the Main Menu, without saving, once you find out whether it works and resume your game with Ophelia.
The cheats that I think you will need.

shift-click on Sim and choose Pack Cheats, Expansion Packs, Get Famous, Public Image, Increase Celebrity Level to make your Sim a celebrity and reach the necessary level. I think you need level 2, Rising Star, to host a Meet and Greet.
Good luck and have fun. Be sure to let us know what you find out, in case anyone else has this question.
