Actor Jerry O'connell has set up shop next to Shia LaBeouf's bizarre art installation in Los Angeles, inviting fans to visit his own parody performance piece.

On Tuesday (11Feb14), the Transformers actor launched a public performance art piece, titled #IAmSorry at 7354 Beverly Boulevard.

Visitors were treated to a face-to-face encounter with LaBeouf, who sat in front of them with the same paper bag he wore over his head at the Berlin International Film Festival on Sunday (09Feb14) with the words 'I am not famous anymore' scrawled across the front.

Local Los Angeles blog reports LaBeouf blinked at visitors in silence, while others sat in a room with him as he "sobbed uncontrollably".

And, on Wednesday (12Feb14), O'Connell teamed up with comedy website FunnyorDie to create his own installation at 7358 Beverly, called #IAmSorryToo.

While LaBeouf still had plenty of eager fans waiting in line to see his exhibition, many curious visitors began forming a queue for O'Connell's pop-up space, where the former child star also donned a brown paper bag over his head that read, "Super Famous" while holding a Dvd copy of 1986's Stand By Me, in which he made his film debut.

According to the FunnyorDie account, O'Connell will only be at the space on Wednesday, while LaBeouf is expected to continue his odd performance piece until Sunday (16Feb14).
