"Thank God for Glam Squads," she captioned the post. "Season finale is TONIGHT on @maskedsingerfox. Hope you tune in." She then thanked all of her glam team: "@beautybyangee @scottkinghair @warrenalfiebaker @formlessbeautybyjenny #makeup #lipgloss #makeuplooks #makeuptransformation #hair #wigs #makeupartist."

Fans were blown away and immediately began commenting: "This is awesome. Thanks for being a real one J," and, "Thank you for showing the world what Hollywood really looks like before the glam you're beautiful both ways."

Jenny revealed how she looks before her glam squad begin

The mom-of-one recently showcased another very different look when she transformed herself into Gwen Stefani for the popular singing show.

Alongside a snapshot of herself looking every inch the No Doubt singer - complete with face gems and a Hollaback outfit - she wrote: "I'm no @gwenstefani but it sure was fun dressing like her for 90s night tonight."

Jenny previously opened up about her appearance and had no problem admitting she loves a little cosmetic procedure to give her a boost.

She told Michigan Avenue magazine: "I think plastic surgery is fun if it makes you feel good. I love Botox, I absolutely love it. I get it minimally, so I can still move my face. But I really do think it's a savior."

Jenny also makes time to work out and eat healthily and this goes a long way towards keeping her looking and feeling her best.
