Reality TV star Shayne Lamas has stunned family and friends by marrying her boyfriend of just a day in Las Vegas.

According to TMZ.com, the daughter of actor Lorenzo Lamas eloped and wed Nik Richie at the Little White Wedding Chapel, where Britney Spears exchanged vows with childhood friend Jason Alexander in 2004, only to have the marriage annulled days later.

The new couple reportedly met on Saturday and wed within 24 hours.

Lamas broke off her engagement to "The Bachelor" star Matt Grant in July 2008 after winning the reality TV competition.

Richie, the founder of celebrity website TheDirty.com, announced the news with a short note on his Twitter.com page on Monday that read "Married".

Lamas has yet to confirm the wedding.
