Steven Tyler - Steven Tyler's Jewellery Designer Confirms Rocker's Engagement

The Aerosmith frontman sparked rumours he is set to make Brady the third Mrs. Tyler after she was spotted wearing a new sparkler on her wedding finger during a Christmas (11) vacation in Hawaii.

The couple, which has been dating since 2006, has yet to address the reports, but now celebrity jeweller Loree Rodkin has confirmed her client's wedding plans and revealed the details behind the gem.

She tells UsMagazine.com that the pricey one-of-a-kind piece features a five-carat brilliant cut stone set on a micro pave diamond and platinum band - and Rodkin is flattered to have been asked to create the engagement ring.

She says, "Having made Steven's jewellery for so many of the past years, it was an honour to be part of his future... with all my love to Steven and Erin."

Tyler was previously married to Cyrinda Foxe from 1978 to 1987, and he divorced Teresa Barrick shortly before meeting Brady.

The couple are expected to make the big news official when they appear together for a rare interview on Oprah Winfrey's new show, Oprah's Next Chapter, which debuts in America on 1 January (12).
