Life on the road can get a bit lonesome at times, but when you're traveling with a friend, it's always an adventure, just ask Rita Ora and Iggy Azalea.

Long before the two teamed up for their collaboration "Black Widow," off of Iggy's album The New Classic, the labelmates traveled Europe in early 2013 for Rita's tour.

So when the two blonde beauties stopped by "Live From MTV" on Monday, we put them to a friendship test, asking them who is more likely to elope in Las Vegas (Rita,) who is their favorite Spice Girl and who is more likely to buy a really expensive pair of shoes (Iggy).

After they passed the test, they looked back on their tour together, which they admit got a bit messy at times.

"She [Rita] has a party bus. I, like, wrap my hair up and clean stuff," Iggy said before later adding. "I have fun. I have OCD that's my problem."

Rita continued, "She'd come on my bus and be like 'This is a mess."

"I get up in the morning and reorganize the fridge," Iggy added. "It annoys me to have a dirty fridge, it's so gross."

However, this self-proclaimed "old lady," certainly has a feisty side, just ask Rita Ora's sound man.

"It was the last day of our tour and I was late on stage by literally five minutes, but he cut my sound off halfway through my last song and I'm like, 'You're the biggest jerk. Just chill out, it's the last show,' " Iggy explained. "So we got all these snowballs and when he was doing the set and he was like 'Can I help you with anything?' and we were like 'yes' and threw it in his face, but he was such a jerk, he had it coming for him, he needed a snowball in his face and it was the last night and its like 'What are you gonna do, kick us off the tour? It's over."
