Shia LaBeouf and Lena Dunham have been arguing about his skywriting apology.

The Transformers star employed a team to write a large message in the sky above Los Angeles on New Year's Day reading "I AM SORRY DANIEL CLOWES," in an attempt to make peace for plagiarising the comic book writer's work, Justin M Damiano in his short film HowardCantour.com.

However, Dunham was less than impressed, writing on her Twitter page: "I've always felt, utterly and unchangeably, that only sociopaths hire skywriters."

LaBeouf retweeted the Girls star's comment and added his own view, saying: "I don't mind creating debate with thoroughly considered artistic expressions but I don't want to offend with a tweet. Sorry world."

Dunham, 27, realised LaBeouf, also 27, was quoting her own character from Girls, Hannah Horvath, back at her, so referred back to his Disney character, Louis Stevens - who he played in Even Stevens between 1999 and 2003 - in her reply.

"Vaguely recognized Shia Labeouf's latest twitter apology and realized it was MINE! Touché, Louis Stevens," Dunham wrote.

"Projecting a lot of rage against my 7th grade boyfriend on LaBeouf. Think this is the start of something really productive #2014. (sic)"

Since his initial apology to Clowes, LaBeouf has purposefully plagiarised apologies from many figures and sources in popular culture and posted them on his Twitter feed.

Clowes has yet to comment on the actor's work, but his editor, Eric Reynolds, says he wouldn't have seen the skywriting, as he doesn't live in Los Angeles.

"I imagine airplane messaging is the norm in Hollywood, but someone really should have informed Mr. LaBeouf that Mr. Clowes lives in the Bay Area [in Northern California] before he went to all that trouble," Reynolds said.
