From Backstreet to BTS: The Boy Band Quiz

For the record, Donnie (Wahlberg, of course) is not just a Leo, but a "loveable Leo" at that.

Yes, Britney doesn't get a mention. And while the boys do sing about a Jennifer, they just don't specify which one (is it Lopez? Love-Hewitt? Who knows!)

Timberlake's vocals sound like he's saying "It's Gonna Be May," instead of "Me," so recent years have seen social media littered with memes featuring the star on the last day of April.

That's right, the group known for its revolving door of members was first formed in 1977, and boys were phased out once they got too old for the trademark youthful sound. Ricky Martin joined the group in 1984, and future star Marc Anthony (that's the former Mr. Jennifer Lopez), was relegated to backup vocals during Martin's reign.

Just call him the last man standing! Originally known as "Rap Monster," the stage name RM now stands for "Real Me" according to this member of the massively popular boy band. Incidentally, his real name is Kim Nam-joon.

Little Frankie didn't get to join in on the boy-banding fun, as he is eight years younger than the youngest Jonas in the group. Still, he's lovingly known to their fans as the "Bonus Jonas." He's done a little acting too.

The role of Alex in "Dunkirk" was quite the way to kick off Styles' acting career, as the World War II epic won big at the box office. Director Christopher Nolan said he was unaware of the extent of Styles' fame when he cast him. Rumor has it that Styles plans to focus more on his acting career than music from here on out.

Bobby Brown launched a successful solo career after getting the boot from New Edition in 1985. The hip-hop super group Bel Biv DeVoe (with the middle name representing Bivens' membership) was another spinoff success story.

At the time, Mark was little more than Donnie's brother, although he would soon achieve some of his own success as frontman for Marky Mark and the Funky Bunch.
