You've never seen the #RHOBH pop star quite like this before.

Eileen Davidson gave Erika Girardi "the coolest present ever," in the words of the songstress, for her birthday in the Season 7 premiere of The Real Housewives of Beverly Hills: a guest spot on her soap, The Young and the Restless (clip above). And now it looks like we're getting the best gift ever, because Erika's appearance on the show will air on Thursday.

In the episode, Erika plays Farrah Dubose, a high-powered real estate agent with an affinity for couture clothing. When she literally bumps into Eileen Davidson's character, Ashley Abbott, sparks fly between the two in a scene that's not too different from what we might see on RHOBH.

As you can see in the below clip of Erika's guest spot, these Housewives have never been fiercer. Plus, their acting is clearly on point, since Erika and Eileen always have love for one another on RHOBH.

Eileen couldn't wait for the world to see Erika's cameo on her show, as she expressed on Twitter Tuesday.

Be sure to catch @erikajayne and me on #YR this Thursday on CBS!! I'm so excited!🎬🌟📽👯 — Eileen Davidson (@eileen_davidson) December 14, 2016

Erika also expressed her excitement over the guest spot by tweeting out the line that her and Eileen's characters say simultaneously as they exit in a huff in the clip.

You wouldn't know it from her performance, but Erika was absolutely terrified acting opposite Eileen on Y&R. “I'm scared to death,” she told ET. “I mean, I'm completely out of my lane!”



Of course, this isn't Erika's first acting gig. She revealed last season of RHOBH that she has had past roles in films like Alchemy and Lowball. Eileen even revealed to ET that they had Erika audition for her Y&R role in order to see what she could really do onscreen.

Eileen had complete faith in Erika's acting skills from the beginning. "It was really fun," Eileen told CBS.com about having Erika on Y&R. "From the moment I thought about doing this, I thought Erika would be good, and she was. She was terrific ... It meant a lot to her. She grew up watching [soaps], and they've always been important for her and her mom and grandma, so this was a cool gift."

Erika even impressed the Daytime Emmy-winning soap star. "I loved the fact that she felt strongly enough about her character and her performance that she could say something [to the director]," Eileen said during her interview with CBS.com. "That just tells you she's a professional. She's been doing her own thing and taking care of her own business for a long time."

Hopefully, this is only the beginning of Erika's newfound acting career.

Erika will definitely find herself in some soap opera-level drama during next Tuesday night's episode of RHOBH, which you can get a taste of, below.
