Sacha Baron Cohen is facing more legal woes - comedian Pauly Shore has alleged a scene in new movie Bruno is taken from his film Adopted.

In Bruno, Cohen's outlandish character collects an African baby out of a box on an airport baggage carousel before turning to the camera and saying, "Angelina's got one, Madonna's got one, now Bruno's got one," in a gag joking about stars who adopt foreign children.

The funnyman reportedly sent Madonna flowers and a sympathetic note during her recent battle to adopt Malawian Mercy James, to apologise for the skit.

And now director Shore alleges the scene bears a striking resemblance to the trailer and tagline for his new film, Adopted - a comedy about the public's obsession with celebrity babies.

According to the New York Daily News, Shore has contacted his attorney and is preparing to take legal action against Cohen.

The Ali G star has faced a variety of legal troubles over his comic creations in the past, including a string of lawsuits from members of the public who alleged they were duped into appearing in his 2006 film Borat: Cultural Learnings Of America For Make Benefit Glorious Nation Of Kazakhstan. Two of the cases were dismissed by the courts last year.
