Before appearing on Drag Race, Willam worked as an actor, most notably playing the recurring role of transgender woman Cherry Peck in Ryan Murphy's medical drama Nip/Tuck.

Between 2012 and 2014, she recorded several songs as part of the group DWV (alongside drag queens Vicky Vox and Detox), including the parodies "Chow Down" and "Boy Is a Bottom", whose music videos were viral successes.

Following the breakup of DWV, Willam formed another drag supergroup, the AAA Girls, with Courtney Act and Alaska Thunderfuck.

[7][11] He later appeared in the TV series Boston Public, Cold Case, The Shield, My Name Is Earl and most notably Nip/Tuck as the transgender character Cherry Peck.

The band was started by Charlie Paulson and Xander Smith and features drag queens Detox, Kelly Mantle, Rhea Litré, and Vicky Vox.

Willam also revealed that she frequently got other contestants high and/or drunk, attempted to steal items from the set such as feather fans and RuPaul-branded Ironfist shoes, and had access to a computer in her hotel room, which was outlawed by production, in order to run her "go-go boy side hustle".

She has additionally claimed to have had sex in the bathroom of Micky's Weho, a local club, with producer Steven Corfe, whom she had previously made apologize to her for asking her to leave Untucked after Willam spoke out about "emotional manipulation" being done to Jiggly Caliente over the one-year anniversary of her mother's death.

As the two were being escorted out of the bathroom after being discovered having sex, Corfe is said to have thrown a cup at the performer on stage that night, fellow Drag Race alum Raven, getting the two ejected from the club.

Outside of the club, the duo ran into more World of Wonder staff members, including Drag Race producer Chris McKim (claimed by Willam to be Corfe's best friend), who had to physically separate the two, as they were still "making out".

[22][23] Belli used the publicity of his disqualification to release his single "Chow Down", which was a parody of Wilson Phillips' "Hold On" that addressed the 2012 Chick-fil-A same-sex marriage controversy.

[7][25] On March 21, Belli released "The Vagina Song", a parody of "Billionaire" by Travie McCoy featuring Bruno Mars as his third single, which had been previously uploaded to YouTube in 2010.

[27] In November 2012, Belli was featured with country music artist Drake Jensen on a cover of Tammy Wynette's "Stand by Your Man".

A comedy segment involving insult humor and video reviews, the series would eventually be renewed for a second, third, fourth, fifth and sixth season that then premiered on Belli's self-titled channel.

The song is a parody of "Girl on Fire" by Alicia Keys and also features an altered version of the "breakdown" from "My Lovin' (You're Never Gonna Get It)" by En Vogue.

[32] On August 14, 2013, Belli was featured along with Shangela, Detox, Raven, Morgan McMichaels, Landon Cider, Shannel, and Courtney Act, in Lady Gaga's lyric video for her single "Applause".

Belli's trio, including Detox and Vicky Vox, called DWV, officially split in June 2014 due to a personal conflict between the members.

[36][37] On January 13, 2017, he released a solo version of the DWV hit "Boy Is a Bottom", in Spanish, entitled, "Es Una Pasiva",[38] which went on to top the comedy iTunes chart.

[44] On July 18, 2018, the first episode of Belli's Drag Race-themed podcast co-hosted with Alaska Thunderfuck and entitled Race Chaser, was published on the Forever Dog Network.

[45] In 2020 Alaska and Willam announced that they would be setting up their own podcast network in collaboration with Forever Dog, Moguls of Media (MOM), featuring a "star-studded roster of iconic drag queens and queer luminaries" to bridge "the past, present, and future of LGBTQ+ entertainment".

Belli was nominated for his role on RuPaul's Drag Race at the fifth annual NewNowNext Awards which aired on Logo network on April 9, 2012.
