As a guest on the Paul O'Grady British chat show Thursday, the singer happily showed off her engagement ring, a non-conflict diamond, purchased by her fiancé Pete Wentz.
Beaming, she held her left hand out to the audience: "He did a great job, it's pretty exciting." Of her husband-to-be, she simply giggled and said, "I got a good one," as the audience applauded.
Simpson arrived in London last week to promote her new album Bittersweet World with Wentz in tow. The couple was spotted arriving hand-in-hand at the Riverside Studios in Hammersmith on Friday morning for Simpson to pre-record one of many TV appearances scheduled during her visit.
So what does her Fall Out Boy fiancé think of her eighties-pop influenced album? "He likes it," she said. "He's such a great supporter of me."
The album title, Bittersweet World, has a more spiritual meaning than some might think. "It's about everyone coming together and it's about (the idea that) you reap what you sow."
Her band, she says, has their own pre-show spiritual ritual. "My girlfriend kisses my hand three times and my band do a really weird ninja dance. We clap our hands and give each other our energy and then we say a really bad word afterwards."
