Jennifer Lopez and husband Marc Anthony have signed a fashion deal with department store Kohl's.

The 'Jenny from the Block' hitmaker - who shut down her luxury sportswear line Sweetface in 2009 - will work on a lifestyle fashion venture with the brand, announcing The Deal at the London Hotel in Los Angeles.

It is expected the brand will be more than just men's and women's clothing and will include home-wear, with Kohl's hoping it could generate up to $3 billion in additional sales.

The Jennifer Lopez range will be added to a number of celebrity-endorsed products at the stores, including Simply Vera by Vera Wang, LC Lauren Conrad and Canadian pop star Avril Lavigne's range Abbey Dawn.

Discussing her previous work, 41-year-old Jennifer claims she only involves herself with projects if she can do something "superclose" to her.

She said: "For me, whenever I get involved with something, I get really involved. Every business that I do get involved with is something that is superclose to my heart."
