Bruno Mars is officially the most fun to go to the Grammys with.

The "Uptown Funk" singer and Grammy winner shared photos on Instagram of how he shared his flask with some of the night's finest stars.

While we can't say what was in the flask, the reactions created pictures worth more than a thousand words.

He first shared a photo of Mark Ronson, his fellow Grammy winner. Thanks to "Uptown Funk," Bruno and Mark won for Record of the Year and Best Pop Duo/Group Performance.

Bruno mentioned the awards in the caption, but he deserves another award for how he celebrated the wins. Bruno wrote, "I'm gettin everybody drunk" as the caption on Mark's photo with his flask.

I'm gettin everybody drunk! Best Collab and Record of the year!

And Bruno did not stop there!

He then shared the drink with Producer of the Year, Jeff Bhasker.

Bruno also gave his flask to Ed Sheeran, who won Song of the Year for his hit "Thinking Out Loud."

While these guys had a lot to cheers about, the flask that Bruno gave them was engraved with lyrics that were not as happy.

"One shot for my pain, one drag for my sorrow" it said. The lyrics are from Bruno's song "Liquor Store Blues."

But with Bruno sitting by you, there's nothing to be blue about when you're drinking liquor together at the Grammy Awards.

Cheers to Bruno!
