Grande ham Miss Piggy returns to theaters Friday

Every once in a while there comes a star so fierce she attains the title of “diva” — Aretha, Cher, Beyoncé. Yet none of them hold a candle to the ferocity of the one and only Miss Piggy.

The world’s most fabulous swine returns to theaters this Friday with “Muppets Most Wanted,” a sequel to the 2011 revamp of the Muppets franchise. This time, the Muppets head out on a world tour, which gets hijacked by the notorious criminal Constantine, who bears a striking resemblance to Kermit the Frog. When Constantine kidnaps and switches places with Kermit for a masterful jewel heist, he wreaks havoc on the Muppets, all while romancing Miss Piggy. Ricky Gervais, Ty Burrell and Tina Fey also join the fun, but the real star is, of course, Miss Piggy. The Post caught up with her to get the scoop on her latest role, how she stays so young and what she really thinks of her fellow Muppets.

Did you have any hesitations about doing a sequel?

No, of course not. I’m always happy to give the world more of moi. But I did have hesitations after I saw the script. Quite frankly, I didn’t have as many lines as I do now. We took care of that. Moi is the proper star of the movie.

Did you have any other demands to participate?

I always ask for a Learjet. In my trailer. I don’t always expect to get the Learjet, but at least I know my trailer’s going to be on the larger side.

Are you angry with Jason Segal or Amy Adams for not taking part this time around?

As a matter of fact, I was very happy. In the last movie, Amy moved in on my big solo and turned it into a duet. Jason, he wrote a wonderful script, but heck, he didn’t have me coming in until like 20 minutes into the film. I’m very happy for them that they’re not in my movie.

When we first met you back in the ’70s, you went by Piggy Lee. Why the name change?

That’s what all celebrities do once they get to a certain status. They just start shaving off parts of their name. Pretty soon they’re just going to be calling me P.

May I ask how old you are?

You may ask. It doesn’t mean I’m going to answer.

How do you stay looking so young?

It’s really no secret. One day I just woke up and decided I wasn’t going to age anymore. I think it’s an overlooked strategy.

Have you tried Botox or plastic surgery?

I was in the formative tests for all of them.

Who do you consider your contemporaries? Judi Dench and Helen Mirren, or ingénues?

I am the perennial ingénue. I don’t know that I have contemporaries, really. I style myself after the great screen legends. The Harlows, the Monroes, the Hepburns. There’s really no one in Hollywood today who measures up.

In 1981 you wrote “Miss Piggy’s Guide to Life,” in which you dressed as Dolly Parton and Bo Derek. If you were to do a follow-up, what style icons would you dress as?

Hmm. I could see myself on a wrecking ball.

You had very curly hair then. Do you regret your perm?

I don’t have any regrets. I mean, I burned that wig, but I don’t have any regrets.

You’ve also gone brunette in the past.

It’s good for a little shock value every now and then. But I’m a blonde at heart.

What celebrity has the best hair right now?

I really love Lupita [Nyong’o]’s look — the really short hair. I’m going to try really short hair soon.

Did you see “12 Years a Slave”?

She did a good job in it — almost as good as what I would do.

You seemed to have a love-hate thing with Lady Gaga on your televised Christmas special last year. How is your relationship now?

We have a lot in common, to tell the truth. We’re both beautiful. We’re both talented. I don’t know if you’ve seen that picture, but we both like to wear frogs around our neck.

What’s the biggest misconception about you?

Some people actually go around saying I’m easy to work with, and I really do take offense to that.

Are you friends with Janice, from the Muppet band the Electric Mayhem?

She’s more of a rock ’n’ roll chick than me. But I have nothing against Janice. Go girl power!

Why are there not more female Muppets?

Well, it might have something to do with I won’t allow it.

Let’s play word association. What’s one word you would use to describe Gonzo?

Weird.

Fozzie?

Not funny.

Ricky Gervais?

Restraining order.

Kermit?

Handsome.

Have you ever considered dating a pig?

I did that once a long time ago. It didn’t go too well.

So you’re exclusively into frogs now?

I am exclusively into Kermit. It’s not that I like him because he’s a frog. That’s like Angelina Jolie being into Brad Pitt because he’s a human.

What advice do you have for getting a man or frog to settle down?

Well, you have to make sure that whoever it is listens to you and can hear your concerns, your hopes and desires. So it’s a pretty good thing if he has ears.
