Adds Mayer, whose fans might think the crooner and the pop star are an odd match: "I'm having the best time of my life, so if the names don't make sense to people, that's so small to me."

Simpson, 26, and Mayer, 29, have been spotted out together for months, including stops in Miami, New York and Los Angeles, but haven't publicly discussed their relationship reports Us Weekly.
In other news, Jessica Simpson has donated a van to a Mexican orphanage.
The actress-and-singer gave the vehicle, which can seat eight people, to the Casa Hogar Elim orphanage in Nuevo Laredo, which she visited in 1999.

The 26-year-old star won a sports car at a swag suite at last year's MTV Video Music Awards but she asked to swap it for a minivan so she could help the orphanage.
A Chrysler spokesperson confirmed: "Instead of the Chrysler Crossfire, she decided to get a minivan for the orphanage instead. She went for the Chrysler Town and Country."
Mama Lupita - who runs the orphanage - reportedly burst into tears when she heard about the gift, and admitted she'd "love to hug Jessica".
The van will be delivered to the orphanage next month.

Jessica is also auctioning off the red dress she wears in her new Pizza Hut advert on eBay. All proceeds from the sale will go to Casa Hogar Elim.
The source added: "The orphanage means so much to her. She wants to help Mama Lupita and everyone there."
