The actors became engaged last year (15), but they have no idea when they will be heading down the aisle, and now the groom-to-be has hinted they may elope to avoid all the stress.

"When we got more into the details of planning the wedding, we both realised, we're pretty horrible at it and we don't like to do it," he told Watch What Happens Live on Tuesday (12Jul16). "So we just keep, like, simplifying everything. We might elope and throw a party at the house."

Dave's fiancee Alison has always been nonchalant about marriage, recently revealing she was too focused on her career to think about settling down and starting a family.

"I never wanted to get married," she told the New York Post earlier this year (16). "I was just like, 'Well, that's not my path in life, because I'm choosing this crazy lifestyle'."

However, that all changed once she met James Franco's younger brother, who made the 33-year-old realise there was more to life than work.

"I fell in love," Alison smiled. "So, blah blah blah, amazing. Acting is fulfilling, but it's also not the only thing."

The couple began dating in 2012 and she revealed the actors immediately hit it off because they share a love of laughter.

"You know how there are no bad kissers, it's just all about compatibility? I feel the same way about a sense of humour," she explained.

Neighbors star Dave proposed to Alison in August (15), popping the question with a unique rose gold diamond engagement ring from California jewellery designer Irene Neuwirth.
