Guess Who

Hidden behind this mashed-up photo is an actor and celebrity who's been around the block since the 80's, and he's no joke! Put your celeb knowledge on the line, or better yet walk the line ... do you think you've got what it takes to outrun this unknown star?

Commonly recognized by his pronounced 'brows, mustache and shaggy beard, this handsome fella is gearing up for the big 5-0 this month. Reprising his role as Arthur, his newest project just dropped earlier this weekend.

Before this blue-eyed blondie sittin' on her mama's lap turned into a dancing queen, she was just growing up with her four siblings in Orem, Utah and started moving 'n grooving when she was just 9 years old.

Considering she comes from a long line of family dancers ... no shocker she's taken home the Mirror Ball trophy twice on "Dancing With The Stars" before sitting at the judges table next to Carrie Ann Inaba.

From the dance floor to the big screen ... You may recall seeing her in "Burlesque" or "Safe Haven."

Before this lil' cutie in her fancy hat turned into an Australian-American actress, she was just growing up in Brisbane with her three siblings and dreaming of seeing herself on the big screen one day!

She first got her start in television on the Australian fantasy teen drama "H20: Just Add Water," however in 2011 she cemented herself as a worldwide star landing the role as Rebekah on "The Vampire Diaries."

From her success, she's used her platform for advocacy like raising money for Boston Children's Hospital and running the New York City Marathon.

Before this cutie pie in her batter's helmet was hitting home runs as an actress, comedian and producer ... she was named after her four siblings who all grew up in Philadelphia, and she was just absolutely obsessed with comedy!

She's paved the way for content creators and comedians dating back to 2014 when she gathered a following on social media and went viral from her "Girl Who Has Never Been on a Nice Date" series.

Still not sure who this could be? She's commonly known for playing the comedic 2nd grade teacher on the hit show "Abbott Elementary."

Before these two happy bros born in Bossier City, Louisiana were in the Hollywood spotlight, they were just all giddy at Disney with their Mickey ears and dreaming of singing and performing on stage.

In 1998, they formed a band in Los Angeles ... While one of these brothers tends to grab the mic front stage, you're more likely to see the older bro drumming up some musical magic in the background.

"Come, break me down, bury me, bury me I am finished with you!"

... You've got "30 seconds" to guess who these two kiddos are!

Before this cute boy with bleach blonde hair was flippin' and floppin', he was just a beach boy in his white tee-shirt growing up in Long Beach, California with his older sister and getting his real estate license at just 21 years old!

He and his former wifey have had quite a successful run on HGTV, and he continues entertaining viewers with his craft and new partner Heather Rae! When he's not flipping houses, he enjoys traveling, partaking in Charli XCX's "Apple" dance challenge and is a doting father to his three kiddos.

Behind these black bangs and altered look is an unforgettable California gal ready to play and slay in her cupcake bra. Given the clues, put your celeb knowledge on the line and see if you've got the skills to score the unknown celeb.

One hot mama ... she's been bloomin' on stage since the mid-2000s and recently flew through the air during her MTV VMA performance. While this singer may no longer be an idol, perhaps she'll still kiss a girl and ... she'll like it! She's the one with the cherry chapstick!
