Talk about an epic photobomb! 

One Direction's Harry Styles and Liam Payne (pictured above, Splash News) appear in the background of a tourist's selfie, which was taken on Machu Picchu in Peru.

Machu Picchu was voted one of the New Seven Wonders of the world in 2007, and for two lucky tourists, South America became even more wondrous thanks to this amazing photobomb.

The epic shot shows two tourists smiling and giving the thumbs up, while the young men of 1D can be seen chilling and taking a break from trekking the 15th-century Inca site. 

The photo, uploaded to Instagram by mrmiatke90, was captioned, "Ticked off two boyhood dreams today, 1. Went to Machu Picchu 2. Met one direction.#onedirection #machupicchu #1D #omgitsharrystyles."

On April 29, Harry and Liam took time off from their world tour to take in the incredible sites of Peru.

Liam seemed to be enjoying the adventure as he tweeted on April 28, "My real job is explorer all the rest of the stuff just part time keeping busy."

One Direction kicked off their "Where We Are" world tour in South America on April 25. They'll perform 67 shows before the global tour wraps.
