The Australian comedian and writer Foster, who announced their engagement in January this year, are reportedly struggling to make decisions about the kind of ceremony that they want.
Foster told the Herald Sun: "We had a weekend where we consciously said, 'Let's work on this guest list' and then failed. I think once we decide big or small, it will be better.
"We've got a big trip to London coming up first and we leave soon, so I've kind of got my head in that space first. A summer wedding would be good."
Foster added: "Maybe we'll run away and elope. But we're such traditionalists... we want all our people around."
Blake also recently revealed that he and Foster have "no idea" when it comes to wedding planning, saying: "They seem very difficult to organise." He also joked that he wants to do some exercise before their big day to make sure his "ass [is] as good as Pippa Middleton's".
