Megan Thee Stallion did triple duty as host, performer and resident hot girl on "Saturday Night Live."

The 27-year-old rapper, who previously served as musical guest in the Season 46 premiere back in 2020, hit the stage at Studio 8H with a few of her catchphrases, alter egos and lyrics in tow for her "SNL" hosting debut.

Megan Thee Stallion donned a sheer black dress topped with a corset for her monologue, celebrating her graduation from Texas Southern University last December.

Fans may know her as Tina Snow, Suga or Hot Girl Meg, but she joked that after touring and making a record while finishing her degree, she's now "Megan Thee (girl) that needs some sleep."

"I got my degree in health administration because I have always wanted to help the people in my community," the "Hot Girl Summer" rapper said. "I believe it's important to have a sharp mind and a sharp body-ody-ody."

She channeled that degree in her first sketch of the night: "Hot Girl Hospital," where three everyday heroes glow up the community "one dusty chick at a time."

With Punkie Johnson and Ego Nwodim as fellow nurses, Megan Thee Stallion in her "Hot Girl Hospital" scrubs chats about her upcoming "weave-oplasty followed by an emergency twerk exam," thanks NBA star Draymond Green for funding the hospital as part of his post-fight community service and helps transform a patient (Heidi Gardner) from "basic" to brand new, complete with a BBL, tight pink dress and long blonde wig.

"When life is on the line, these are the three women who will answer the call, say something rude, then hang up," the voiceover says.

Megan Thee Stallion kicked off her first performance of the night with "Anxiety," off her sophomore album "Traumazine."

In a red Jessica Rabbit-esque gown and a "Miss Anxiety" sash, the rapper channeled the pageant world while she rapped about bad girls having "bad days, too," surrounded by her crown-wearing backup dancers who also sported sashes as Ms. Overworked, Ms. Underpaid, Ms. Overlooked, Ms. Overwhelmed and Ms. Insecure. An emotional Megan Thee Stallion wrapped the performance with tears in her eyes and a big smile on her face.

Her second performance, a medley of "NDA" and "Plan B," showed off a different version of the rapper. In a black corset top and cutout jeans combo, topped with sunglasses and large Cuban link chain, Megan dominated the stage with a confident flow and powerful delivery.
