Britney Spears and Celine Dion may soon welcome a new high-powered female act to the Las Vegas Strip.

Jennifer Lopez is close to signing a deal to perform at The Axis at the Planet Hollywood Resort & Casino, according to TMZ. The offer has her earning $350,000 per show for 72 shows over a 1 or 2 year period.

J Lo will perform three shows a week for 24 weeks. The contract will guarantee her $26,383,326.

Britney Spears also has a residency at The Axis. The outstanding ticket sales for the "Britney: Piece of Me" show brought Spears' people back to the negotiating table and had Planet Hollywood raise her per show earnings from $310,000 to $475,000, according to TMZ.

The contract amendment will give the "Gimme More" singer back end, merchandising and other perks. Planet Hollywood also added more shows to Spears' two-year residency, bringing her total up from 96 to 140 concerts.

The new contract rivals Celine Dion's that has her making $476,000 a show. She brings in a total of $33,320,000 for her 70 shows a year at The Colosseum at Caesar's Palace.

Dion had to cancel the rest of her performances through March 22, 2015. She wanted to focus "100 percent of her attention" on her husband René Angélil, their family and recent health issues, according to statement made on her Las Vegas show page.

"I want to devote every ounce of my strength and energy to my husband's healing, and to do so, it's important for me to dedicate this time to him and to our children. I also want to apologize to all my fans everywhere, for inconveniencing them, and I thank them so much for their love and support," Dion said.
