An engagement between Aniston and Mayer?

Singer John Mayer has approached top U.S. jeweler Lorraine Schwartz to design a ring for girlfriend Jennifer Aniston, according to Mirror.co.uk – and the budget is pretty much limitless.

Lorraine Schwartz has made rings for J-Lo, Heidi Klum and Beyonce, among other celebrities, according to Mirror. Jen’s ring will likely include an 18-carat diamond.

The only secret left is when will he propose?

Jennifer ended her marriage to Brad Pitt in 2005. She later dated Vince Vaughn and began dating John last year. Her most recent movie is “He’s Just Not That Into You.”

When do you think John will propose?
