“I didn’t want her to see me coming in and ruining the surprise,” she added. “I can’t wait to see if it works.”

Later in the video, Melissa revealed the moment she pulled off her epic surprise.

“Holy mother of Christ,” Mariska, 62, said after Melissa walked into a room to greet her. “Are you f–king kidding me?”

The pair can then be seen sharing a few quick hugs, as Melissa admitted that Mariska was “very hard to trick.”

“Mariska, you are the real deal,” Melissa added in the caption. “Sorry everyone lied to you, hope it was worth it (this surprise was six years in the making people)!!!”
