The Celebrity Big Brother legacy continues tonight (Jan. 3) in the UK with the premiere of All Stars and New Stars, a competition combining fan favorites from past seasons and newcomers alike.

Following much speculation regarding this season's cast, we finally know who's officially entering the house, which has been given a "sexier" redesign, thanks to The Sun.

Heidi Montag and Spencer Pratt, who notoriously shook up the CBB scene with their run on the 11th season in 2013, will return to duke it out for the top spot together as Speidi.

Ray J, evidently taking a break from Love & Hip Hop Hollywood, will make his CBB debut.

This year's roster also includes Lindsay Lohan's ex Calum Best, who competed in the 15th season in 2015, ballroom dancer James Jordan from the 14th season in 2014, US model Austin Armacost from last year's Celebrity Big Brother: UK vs USA, UK model and TV personality Nicola McLean, who appeared in the ninth series in 2012, US actress Jasmine Waltz, who appeared in the 13th season in 2014, and Loose Women panelist Coleen Nolan, who appeared in the tenth series in 2012.

Newcomers include former X Factor USA contestant Stacy Francis, footballer Jamie O'Hara, British DJ Brandon Block, Game Of Thrones actor James Cosmo, former Playboy bunny Angie Best and model and TV personality Bianca Gascoigne.

As always, the star-studded (?) competition promises to be one messy affair.
