Will second time be the charm for Crackhouse and her whacked out ex?

Amy Winehouse is reportedly set to tie the knot with jailbird former husband Blake Fielder-Civil in a Las Vegas ceremony….just as soon as the heroin addict wraps up his latest stint in rehab!

Ain’t love grand?

“They will definitely be getting married and have agreed on Vegas. Amy doesn’t want a traditional ceremony and wants it to be similar to their first wedding,” The Sun claims. “Amy and Blake have cleaned up their act and want a fresh start. She picked the new pad because it is big enough to be a family home.”

The “Rehab” star — who was previously denied a US Visa for drug possession and assaulting a fan — needs to get the all-clear from authorities before she and Blake can fly out to plan the ceremony.

Blake and Amy- who reconciled earlier this year, just months after divorcing – originally eloped in Miami in May 2007. Although the pair are planning a similar laid-back approach to their nuptials, have opted for a different American city because the Grammy-winning singer is frightened returning to Florida could be disastrous for their relationship.

“She chose not to marry in Miami again because she thinks it could be a bad omen. She can’t stop talking to people about their future together.”
