Angelina Jolie keeps photobombing Elle Fanning on the set of 'Maleficent 2'

Angelina Jolie is one celebrity who has managed to stay off Instagram all these years. While others enjoy the bombardment of hearts directed at their selfies, or use the platform to announce exciting news and to promote upcoming pursuits, the 42-year-old has long refused to join the social media site.

But now, she's made her debut. The first time she's voluntarily posed for a photo that was intended to be uploaded to Instagram is here, and it's just glorious. No, it's not on her own profile, but in an intentional photobomb of someone else's – which makes it so much better.

The actor, mother and activist just started filming the sequel to Disney's Maleficent, and it seems like she's been unable to stop photobombing her costar's Instagram selfies. 20-year-old Elle Fanning, who plays Aurora (AKA Sleeping Beauty) has been sharing photos on set from Maleficent 2, and Angelina keeps hilariously popping up in the background.

Elle uploaded one photo on Tuesday showing Angelina in a fluffy white bathrobe and her hair and makeup done in full costume – Maleficent horns, pointy teeth, bold red lipstick and all. The tiny sunnies, I guess, were just incidental.

Elle's hair was done to fit her princess persona – soft waves and braids flecked with tiny flowers. Taking a selfie, Elle laughs as you can see Angelina jump into frame in the background while posing. The caption reads: "It's bring your mom to work day on the #Maleficent2 set!!!!!"

It's implied that Angelina's character will continue to play something of a mother-figure to Elle's Aurora in the sequel, where they will also be joined by Michelle Pfieffer and Chiwetel Ejiofor.

And as if that wasn't enough, Elle uploaded another selfie on set, which – you guessed it – Angelina snuck into as well.

"Ultimate Photobomb #Maleficent2," Fanning captioned the second selfie, where you can see Angelina aligning herself so that only her horns are visible behinds Elle's head.

At the beginning of May, Elle (Fanning) spoke with Elle (the magazine) about working with Angelina again for the sequel, as well as what it was like to return to the character of Princess Aurora after a few years.

I've never done a sequel before, so it should be fun to revisit a character many years later. That is something I'm very excited for," she said.

"Also, being reunited with Angie is pretty cool. She's just a powerhouse on set; the way that she works, she just has this power and respect around her. It's so funny because people always ask, 'Oh, does she give you advice all the time?' and it's not so much like that.

I think just watching her… and seeing what a great mother she is. All of her kids are there and she's walking around—like, last time I remember, she was walking around in the whole Maleficent outfit with two kids on each arm. She's a working woman and a mother, and that example is such a great one for me to see. You can do it all."

Good luck to them on the new film, although it seems like they'll do just fine judging by the amount of fun they're already having.
