Broadway is gearing up for Tony night, when the theater crowd lets loose.

Beyond the awards’ official fete at The Plaza, “parties are being planned in homes, restaurants and ballrooms,” said a showbiz spy.

Tonys host Hugh Jackman hinted where he might kick up his heels after the show by mysteriously posting an online picture this week of Bobby Van’s Steakhouse with the caption, “A hint.”

The meat mecca is where “Beautiful: The Carole King Musical” will have a bash.

After all the shows celebrate, top theater PR firm O&M Co. will throw its annual swanky late-night soiree at the Carlyle, which is usually punctuated by a 2 a.m. champagne toast to one “theatrical luminary.”

But, we hear, this year the toast will depend on the night’s best musical winner — and will either be a 3 a.m. tea in celebration of “A Gentleman’s Guide to Love and Murder,” an early morning dance party at Café Carlyle for “After Midnight,” a piano performance at Bemelmans Bar for “Beautiful” or a special celebration for producer Thomas Schumacher if “Aladdin” takes the crown.
