Singer Kimberly Wyatt is wary of exchanging vows with her longterm boyfriend as she's unsure if she "truly believes" in marriage.
The former Pussycat Dolls star began dating actor Kevin Schmidt in early 2009 and the pair has discussed making its union official - but Wyatt remains unsure about walking up the aisle.
She tells Britain's Look magazine, "I'm not sure if I truly believe in marriage. We've talked about promise rings, but my anxiety levels went so crazy I had to step outside for some fresh air."
