Jenna Ortega and Paul Rudd had an "awkward" first-ever meeting inside an airport lounge

Speaking to 'Extra', Jenna explained: "I was writing in my journal and we already knew we were doing the movie together, and I was doing 'Beetlejuice' and you were doing 'Ghostbusters' and we both were in London."

Paul added: "I saw you sitting there and I'm like, 'Oh, my God, I think we're gonna be working together on this thing pretty soon,' and I went over and said hello, but I wasn't sure if it was you.

"I walked over - I did that approach like, 'Is that...?' Then I felt a little stalkery."

Jenna recalled being caught off-guard by her co-star.

The actress shared: "I felt like you were standing there for a while because when I write, sometimes, if I don't know what to write and I kind of was getting to the end of my page anyway, I'll just write exactly what's happening in the moment, and I was like, 'Oh, this guy's been staring at the, you know, board for a really long time,' and then I looked up and it was Mr. Rudd."

Paul continued: "There was that moment where I'm like, 'I think that's Jenna.' I haven't met her and you're in that awkward space where, like, I guess, I'm gonna look at the departure board to make it - in case it's not ... And then finally, you looked up."

Despite her own fame and success, Jenna recalled feeling a little "nervous" at the time.

The 'Wednesday' star said: "I was kind of nervous, I think, because it caught me off guard, and I was kind of in a weird place in my life, so I had a bit of a jump scare."
