Ellen DeGeneres is being sued for making a boob joke on her chat show.

Titi, who is a real estate agent, says she was mocked in the piece on 'The Ellen DeGeneres Show' because the presenter changed the pronunciation of her name to "titty" - which means breasts.

She says nobody has made the mistake in 35 years and she "suffered stress, emotional distress, embarrassment, humiliation, anger, and other mental pain and suffering" according to court papers obtained by TMZ.

The documents submitted also state Titi's mobile number was flashed across the screen and this led to her receiving 'ridiculing and harassing phone calls and voice mails' while she was at a funeral.

Titi is suing for "defamation, false light invasion of privacy, misappropriation of likeness, and intentional infliction of emotional distress."

Elsewhere, Ellen – who is married to Portia di Rossi – recently admitted she doesn't regret not having children because she doesn't think it would be fair to raise them in the spotlight.

She said: "I think in this profession it can be really tough for children. It's hard for them to have to share their parents with the world."

The former 'Ellen' star added it can be tough enough when she's out with her nieces as the girls find it frustrating having to share her with other people.

She said: "When we're out in public and people want to talk to me they're like, 'Why does everybody want your time? Why aren't you just with me?' "
