Justin Bieber Just Reignited His Bizarre Beef With Tom Cruise During His 'Bottle Cap Challenge' Video

Justin Bieber is at it again.

Despite seemingly backing down in his initial challenge of an MMA fight with Tom Cruise, the star has once again called out Tom Cruise for a fight.

Can anyone tell me what Tom Cruise did to Bieber? Anyone?

I'm at a loss here.

The popstar took part in the bottle cap challenge that has been going around the internet. He uploaded a video to Instagram to demonstrate his ability.

It's less impressive than some of the videos you've seen.

While the caption is an innocuous nomination of Cruise and Bieber's wife, Hailey Baldwin, for the challenge, the video itself tells a different story. Before he runs up to the bottle, he says,

"This could be Tom Cruise's head."

Could the Biebs really take Tom Cruise in a fight?

Despite his backpedaling, it really seems like he wants to.

His Instagram comments were a mixture of support and telling him to back off.

Obviously, this is Bieber having a bit of a joke at the expense of himself. He knows by now the original challenge was a weird one to make.

He even said the Mission Impossible star would "whoop [his] ass" in a fight. However, the fact he keeps bringing it up has some people really wanting to see it.

And I mean, REALLY want to see it.

The initial tweet led to a spate of challenges against other stars who are 31 years older than their challengers. This was a strange mix as people called out the likes of Sam Waterson, Sally Field, and Jackie Chan.

(Side note: Sean Bean, if you're reading this, my challenge still stands. Anytime. Anywhere.)

Bieber has claimed it was just a bizarre joke, a random tweet like he sometimes does. But I'm not buying it.

This is too often and specific.

We gotta ask: Why Tom Cruise?

In the strange month since the initial challenge, Cruise has not responded or commented on the possibility of a fight with Justin Bieber. Which is understandable.

That said, Hailey did take the challenge her husband gave and performed her own bottle cap kick from a four-wheeler.

Maybe she could fight Tom Cruise in Bieber's place?
