Pico Alexanders leading lady came to his dressing room the other day with a suggestion. It would be better the way we did it before, Sherie Rene Scott told him, when you were f–king the s–t out of me!

And she was right, Alexander tells The Post over baklava and coffee at a Midtown restaurant: Now their bedroom scene in The Portuguese Kid has a lot more energy.

So has his career. After a string of small roles, Alexander played Reese Witherspoons young lover, Harry, in Home Again. Even moviegoers underwhelmed by that September release were wild about Harry.

Women around the world are tweeting multilingual variations on Pico Alexander is SOOO hot!

And now hes onstage at the Manhattan Theatre Club, where John Patrick Shanleys comedy about mismatched lovers opened Tuesday. Jason Alexander stars as a lawyer of George Costanza-like ineptitude; Scott is a lusty, 50-year-old widow and Pico Alexander (no relation to Jason), her 20-years-younger lover.

That hes just played back-to-back boy toys hasnt gone unnoticed.

People are, like, Why are you always hooking up with these older women? says the lanky 26-year-old, sounding like the Brooklyn native he is. I think its just the luck of the draw! He says hes yet to have a real-life May/December romance but wouldnt rule it out. (Older women of the world, take heart.)

He was born Alexander Jogalla, but his grandfather dubbed him Pico while he was in utero, and the name stuck. Growing up in Park Slope, he visited movie sets with his cameraman dad and met Hugh Jackman while the X Men star shot 2001s Kate & Leopold.

Not only did Jackman take photos with young Pico, but he mailed them to him, signed with Wolverines signature greeting, Hey bub. They did a reading together a few months ago, and Alexander was struck again by Jackmans kindness.

I admire that more than anything, he says. Who has time for some actor whos a total pk?

So far, it seems, hes liked everyone with whom hes worked. He calls Jason Alexander a comedic genius and admires Witherspoons willingness to banter with everybody on the set. Theres not a speck of diva, he says. None!

While he speaks, he twirls what looks like a wedding band. Its not just a ring his mother bought him when she visited India, a place he hopes to see one day himself. For now, he lives in Brooklyns Ditmas Park with two totally platonic girlfriends hes known since they were bandmates at Mark Twain Intermediate School 239.

He says he closed his Instagram and Facebook accounts two years ago. I felt I was spending too much time on it, comparing myself to my peers and sometimes complete strangers, he says. Hed rather read the news or go to Central Park, just a few blocks from the theater, to feed the turtles.

Mostly, he says, hed like to travel. I have no kids, no mortgage, he says. I want to have some adventures.

For now through Dec. 3, he has The Portuguese Kid. With two hours to go till showtime, he gives a goodbye hug and heads for the park to feed the turtles.
