There's nothing more hilarious than a celebrity photobomb!
Hugh Jackman snuck up on a reporter on live TV in Australia this week after leaving a local hospital to visit sick children as part of his work with the Fight Cancer Foundation.
The Aussie actor ran up behind reporter Jessica Turner while she was doing a standup and said "Photobomb" as he passed.
Jessica turned to see the "Wolverine" star and said, "The best kind of photobomb, Hugh!" Check out the funny moment below!
But Hugh wasn't the only superstar to thrill his fans this week!
Sam Smith is back on the road, hitting up Denver's Red Rocks Amphitheater the other day.
While he was there, he just happened popped up on 7 News, who was interviewing fans about the venue where he show was taking place.
In the clip above, you can see the "Stay With Me" crooner flashing peace signs behind a set of interviewees -- and they never realized who he was. Smith was even urged to leave!
We're betting they're kicking themselves today for not noticing the singer.
