Dwayne ‘The Rock’ Johnson says Zac Efron has “soft lips”

When asked what Zac’s lips feel like, Dwayne first joked: "Millions and millions of young ladies, and ladies in general, want to know ... His lips were like if you have a bottle and you shatter it on the ground - that shattered glass.”

The ‘Central Intelligence’ star then clarified that Zac does in fact have "soft lips.”

However, 29-year-old Zac doesn’t share the same fond memories of their on-screen kiss, as he says kissing co-star Alexandra Daddario was a much more pleasant experience.

Asked which of his co-stars was a better kisser, Zac told ‘Entertainment Tonight’: “She (Alexandra) was a better kisser for sure. But it was funnier to look up and see Dwayne's face.”

Meanwhile, fellow ‘Baywatch’ star Kelly Rohrbach admitted the cast - which also includes Priyanka Chopra - “cheated” when getting into shape for their roles, as they all had personal trainers to help them reach their goals.

She said: "I cheated. We all cheated because we had trainers. We had trainers while we were filming and trainers before we were filming, which was great, because you don't have to think - you just do as you're told.

"I did a lot of running. I ran the beach in LA four or five times a week - sprint sets and stuff. I like to box so I did a lot of that with my trainer. Then I did weights. I would start working out so early in the morning I'd be half asleep.

"By the time I got back into my car, I didn't remember what we just did. You sort of want to black it out, working that hard."
