Supermodel-turned-TV presenter TYRA BANKS has dismissed rumours she is engaged to her businessman boyfriend after she was snapped wearing a diamond sparkler on her ring finger.

The America’s Next Top Model host prompted speculation she was set to walk down the aisle with John Utendahl when she was seen wearing the jewel after a dinner date in Los Angeles on Saturday (29Aug09) with her boyfriend of two years.

But Banks’ representatives have shot down talk of a wedding, insisting the ring is a sentimental piece of jewellery from her school days.

Her spokesperson tells GossipCop.com, “Tyra is not engaged – it’s her high school ring and she wears it almost every day.”
