Jared Leto recently pulled off another prank at the LACMA's 2015 Art+Film Gala, according to E! Online.

The actor, who plays the Joker, photobombed Diane Kruger as she posed for photographers during the event.

Was Diane Kruger pissed off that the "Suicide Squad" actor ruined her moment at the event?

Not quite. In fact, she instagrammed a photo of herself with the Joker actor.

"Just you wait, I'll get you back... @jaredleto," Diane captioned the photo.

Jared Leto's photobombing may be a lot tamer than his previous prank aimed at his "Suicide Squad" co-star, Margot Robbie, who he allegedly gifted with a rat on set.

Jai Courtney, who plays Captain Boomerang in "Suicide Squad" dished out to MTV about how dedicated Jared Leto was to his role as The Joker.

"I don't think any of us are naïve to the pressure he's under," Courtney said. "It's not something I've talked about with him, but I've seen him working and it's cool, man."

When asked if Jared Leto has gone method acting for his "Suicide Squad" role, Jai Courtney was quite unsure of the answer.

"Sort of," Courtney said. "I don't know how you measure that these days. I haven't seen him, since we started working, out-of-character, let's put it that way."

It has earlier been reported that Jared Leto has given his "Suicide Squad" co-star Margot Robbie a rat as a gift, saying that it's from The Joker.

E! Online previously reported that director David Ayer employed the help of a therapist on set for the entire "Suicide Squad" cast.

"David Ayer is about realism," Adam Beach, who plays Slipnot in the film, told Marc Malkin of E! Online.

"So if your character is tormented, he wants you to torment yourself. He wants the real thing ... We kind of have like a therapist on board if you fall off the wagon and really are villainous. There's a friend of [Ayer's] that's very unique in making sure we have our ground."
