Lady Gaga is suing a cosmetics and jewellery company for trying to use her name on its products.

The Grammy Award-winning pop star is suing Excite Worldwide LLC in New York.

The lawsuit says the company applied without her permission to trademark the names Lady Gaga and Lady Gaga LG for a make-up and jewellery range.

Excite Worldwide didn't respond to telephone messages at numbers listed for the company in Chicago and Henderson, Nevada.

Official merchandise

Lady Gaga is in the process of developing her own range of products.

The singer has registered her name for clothes, ringtones, her website and chat rooms and has trademark pending for hair, body and nail products.

The lawsuit says customers could be duped into thinking she's affiliated with Excite Worldwide's products. She's seeking unspecified damages.

This is not the first time Lady Gaga has taken action to protect her name.

In March, she took legal action against an ice cream shop in London selling breast milk ice cream under the name Baby Gaga.
