Here's where you recognize the cast of 'Celebrity Big Brother' from

• The US version of "Celebrity Big Brother" first aired on CBS in 2018 and it's now in its second season.
• In "Celebrity Big Brother," houseguests play to win money for a charity of their choice.
• This season, stars like Dina Lohan, Ryan Lochte, and Tamar Braxton entered the house. 

The second season of "Celebrity Big Brother" kicked off in January on CBS and a fresh wave of house guests checked in for their month-long stay. On February 13, one competitor will take home a generous prize of $250,000. But who's playing to win this season?

Here's where you know the season two cast of "Celebrity Big Brother" US from. 

Jonathan Bennett was in "Mean Girls."

Bennett is best known for playing Aaron Samuels in the 2004 hit comedy "Mean Girls." Following his role as Regina George's high-status man candy, Bennett hosted "Cake Wars" and "Halloween Wars" on The Food Network, placed ninth on season 19 of "Dancing With The Stars," and made a cameo in Ariana Grande's "Thank U, Next" music video. 

Ryan Lochte is an Olympian.

Ryan Lochte is a six-time gold medalist on the United States Olympic swim team. People called him the second most decorated swimmer in history, but he's also among the most controversial swimmers.

In August of 2016 The New York Times reported that during his time at the 2016 Olympic Games in Rio, Lochte and a few of his US teammates had been robbed by locals in Brazil when, in reality, the swimmer had been "drunk and unruly," damaging property at a gas station after a party.

Although the 34-year-old is suspended from swimming until July of 2019, according to ESPN, you might've caught Lochte on season 23 of "Dancing With The Stars."

Joey Lawrence has been in a few notable shows.

To 80's kids everywhere, Joey Lawrence will forever be known as heartthrob Joey Russo on "Blossom," but the eldest Lawrence brother has starred in a handful of sitcoms from NBC's "Brotherly Love" alongside his real-life brothers Matthew and Andrew in the mid-90s, to Freeform's "Melissa and Joey."

He also came in third place during the third season of "Dancing With The Stars" back in 2006.
