Engagement rumors are mounting, hitting celebrity power couple Justin Timberlake and Jessica Biel.

It is reported that Justin has been spotted shopping for engagement rings at famous New York jewelery store Tiffany and Co., and is planning to propose to his actress girlfriend Biel.

“Justin was really taking his time looking round the rings. He made the staff get a couple out of the cabinets so he could properly look at them,” an onlooker revealed. “He didn’t buy anything but told the manager he would think about it.”

Justin and Biel have been romantically linked since early last year yet remained tight lipped whenever they’re asked about their relationship.

No words from the couple concerning the engagement report.
