Believe it or not, it's a tie!
Well, actually, Adam Sandler and Jennifer Aniston's Just Go With It barely edged out Justin Bieber's Never Say Never for the number one spot with $31 million, BUT it's such a tight race that the number one movie could change by the time Monday morning's figures come in.
By Sunday morning, Never Say Never brought in $30.3 million, which means it could easily take the top spot!
We're sure Beliebers will try their hardest to make that happen!
Meanwile, the animated film Gnomeo and Juliet came in third place with $25.5 million, which made the Valentine's weekend a pretty successful box office weekend.
So, we have to ask…what did U see this weekend?
