We've all tweeted something we've regretted, right? Well Charlie Puth certainly regretted this gem of a faux pas when he spotted Harry Styles whilst out for dinner one night.

When the 'Dangerously' singer came in to see us recently, Puth told us about the first time he was super star struck and apparently he used to be a total fanboy over One Direction star Styles...

'WATCH CHARLIE PUTH TELL US HIS HARRY STYLES STORY HERE:'

"When I first came to sign my record deal in Los Angeles," he began, "I was having a meeting with the record label in a Sushi restaurant called Sushi Park on Sunset Boulevard and Harry Styles walked in with my now-friend Jeff Azoff. I couldn't even concentrate on eating, I was so star struck.

"We joke about it now," he continued,"but I ended up during the dinner tweeting, not at Harry, but just tweeting like, 'wowI can't believe Harry Styles just walked into my sushi restaurant!' And then this influx of paparazzi and fans just from that tweet came in, so I was pretty embarrassed.

"[Harry] pokes fun at me now like 'you're not gonna tweet that we're at this trailer now are you?!'"

See, look at that pic. Best buds now.
