Jessica Biel reportedly begged strangers to help her find her engagement ring only to realise she hadn't lost it.

Jessica was recently playing with her dogs in the park and as she drove away she became terrified her ring had flown off during the rough and tumble.

The star immediately began begging passers-by to help her search for the gem, before frantically calling her friend.

"She reminded me I hadn't been wearing the ring when she'd seen me earlier. I'm so sorry to put all you guys through this," Jessica is quoted as saying by National Enquirer.

It's not the first time Jessica has been a nervous wreck about her ring. The star laughed she thought she'd lost it after going on a run recently.

"Justin reminded me that I hadn't been wearing it. I guess I subconsciously keep taking it off when I go places where I think I might lose it," she laughed.
