Everyone loves a good photobomb — even celebrities.
These are the most serendipitous encounters normal people have had with celebrities photobombing them, including Dwyane Wade's sweet reaction to a proposal and the iconic "double-bomb" of Arnold Schwarzenegger and Sylvester Stallone.
Be on the lookout in your photos — you never know who'll show up.
In another case of celebrities being just like us, they love a good photobomb. They do it to each other on red carpets all the time.
But these cases are special — these famous faces actually chose to bless regular people with their presence, and memorialize it with a photo.

The former NBA superstar was walking along the beach in Montecito when he happened to walk right by an in-process proposal.
Instagram user @ryanbasch shared a series of three photos of Wade walking behind the happy couple and eventually taking a photo with them. He captioned the photos, "When @dwyanewade happens to be taking a sunset stroll on the beach and walks by mid-proposal."
Wade even shared the photos to his Instagram story, and DMed Basch himself, writing, "I need y'all marriage to work. It's now on my conscience." Basch eventually invited Wade to the wedding — so perhaps we'll see more of this unlikely friendship.
