Big Brother's Season 21 houseguests have been revealed by CBS.

The cast of the new Big Brother season -- which will premiere with a two-night premiere on June 25 and 26 -- features 16 houseguests from all across the country, with each person bringing his or her own unique look, background, set of skills, and personality traits to the table.

Among Big Brother's Season 21 houseguests are a preschool aide, a Broadway performer, a petroleum engineer, a therapist, and a truck driver.

And what would a Big Brother cast be without a few models and fitness trainer types?

Big Brother's Season 21 cast also includes Holly Allen, the ex-girlfriend of former The Bachelor: Winter Games villain Luke Pell.

Holly was the on-again, off-again girlfriend Luke reconciled with last year and used as the explanation for why he "ghosted" on Stassi Yaramchuk following their appearance on The Bachelor Winter Games.

After its two-night premiere, Big Brother will continue airing new Season 21 episodes three nights a week through late September. 

Big Brother Season 21 will then conclude with a special 90-minute live finale on Wednesday, September 25 at 9:30PM ET/PT, immediately after the special 90-minute premiere of Survivor: Island of the Idols, the 39th season of Survivor.
