Megan Fox, Machine Gun Kelly Put Their Love To Test With 'Couples Quiz' [Watch]

Power couple Machine Gun Kelly (MGK) and Megan Fox have spilled the beans on their bucket lists, tattoos and relationship, including how they just "breathed each other" on their first date.

The couple took the “British GQ’s” couple quiz, during which they took turns to ask each other questions. Fox started off the playful interrogation by asking MGK how many tattoos she has, and if he remembers the William Shakespeare and Friedrich Nietzsche quotes inked on her body.

The "Papercuts" singer did not recall the quotes, causing Fox to give him half a point for answering the question somewhat correctly.

She then went on to ask him about the number one thing on her bucket list, which he answered correctly as “being abducted by a UFO.”

At one point the “Jennifer’s Body” actress asked Kelly to list one of her hidden talents, which led to him raising his eyebrows, making Fox a little nervous "No, Buddha don't you dare," she said, calling him by a nickname. "Don't you dare. Only PG-rated answers."

And the “Paper Cuts” singer then went on to praise her for her intelligence.

For MGK's turn, he also started with the tattoo question, which Fox had a hard time answering. "It's literally impossible to calculate because you tattooed on the top of your tattoos, so I couldn't say," she responded.

During the interaction, they also shared the details of their first date, which was at a Topanga Canyon picnic full of sushi and roses.

"Our first date we breathed each other. That's what we did," Machine Gun Kelly recalled. "And then our second date…"

And though they didn’t mind spilling quite a lot of secrets during the quiz, they remained tight-lipped about some questions. The “Transformers” actress asked MGK about her favorite way to decompress, for which, the "Bloody Valentine" star replied with a question of his own.

"Do you want to tell them what the doctor said?" MGK asked before Fox insisted, "We cannot say that on camera."

And just when it looked like the musician was going to spill the beans, the footage cut out.

"You are insane," the Transformers actress told her boyfriend. "We cannot say that on camera. That's your favorite way for me to decompress after a stressful day. What's my favorite way to decompress after a stressful day?"

MGK, whose real name is Colson Baker, went on to ace this question as well, as he listed drinking tea, having a foot massage, watching a show together, and having a good cry as Fox's favorite ways to relax.
