Happy V-Day in July, lovers.

This week’s installment of “And Just Like That” is brimming with pinks, plaids, and ghosts of boyfriends past as our favorite fifty-somethings take on February’s notorious Hallmark holiday.

First up, Carrie Bradshaw (Sarah Jessica Parker) gets her long-awaited reunion — drumroll, please — with Aidan Shaw (John Corbett). But, in classic Carrie fashion, she makes a few wrong turns along the way.

When Aidan asks her to Valentine’s Day dinner, Carrie, Miranda, and Charlotte dissect his e-mail (à la Nora Ephron) for clues as to whether Carrie’s former fiancé is flying solo these days.

Carrie arrives at her 8:00 pm date at a fashionably late 8:07, where she is greeted by a table for two with zero ex-boyfriends in sight. After a full half hour, during which Carrie wonders if she’s been stood up, she realizes that an ill-placed address number threw her off.

As Carrie dashes next door, she meets Aidan standing in the street, tall and handsome as ever.

They share a long hug and Aidan says to her, “When I’m with you, it’s like ten years just…” he trails off and snaps his fingers.

It’s a touching reunion with Miss Bradshaw’s one-that-got-away, and it ends with the two of them on Carrie’s same stoop from two decades ago, where their whole relationship fell apart. Aidan gets cold feet when he’s confronted with the apartment where all of his and Carrie’s skeletons still live.

“I can’t do it,” he says, over Carrie’s protests. “I’m not going in there again with all that.”

But one wide-eyed look from Carrie gets them back on the same page.

“F–k it,” Aidan says. “This is New York. They have hotels, right?”

Carrie’s not the only one with a hot date for Valentine’s.

A couple months after the big break-up, Miranda Hobbes (Cynthia Nixon) kicks off this week’s episode trying to figure out if she’s gay gay or if she was just Che gay (Sara Ramirez’ single scene this episode sees Miranda and Che bringing a stray puppy to an animal shelter).

Meeting hot lesbian audiobook narrator Amelia Carcy — whose Jane Austen recordings Miranda used to jog to — immediately settles the question. The ladies set a Valentine’s Day dinner, giving Carrie the chance to tease Miranda about her “Great Sexpectations” for her literary lady.

“Could Ms. Carcy be your Mr. Darcy?” Carrie quips.

Unluckily for Miss Miranda, her sotto voce sweetheart turns out to be a slob with dirty sheets and an evil cat named Pickles. But during a classic mid-date phone call with Carrie, she finds power in realizing that — as a 56-year-old on the dating scene — she can just go home. Not such a bad début for newly-anointed “lesbian Miranda” after all.

Our other fabulous singletons, Seema Patel (Sarita Choudhury) and Nya Wallace (Karen Pittman) don’t have time for romance this episode. When a spa schedules Carrie and Seema for a couple’s massage owing to their Valentine’s policy, Seema threatens to cause a “Yelp” storm, but Carrie rushes her out before she can start a “February 14th spa insurrection.”

“Single people have rights, too!” Seema yells.

Nya takes her first Valentine’s Day post-divorce more in stride, and declares that she will be having a “me-vening.” She whips up a chocolate soufflé for one and decides that the only “body” she needs at her table is a full-bodied glass of red wine.

Switching over to our married crowd, Charlotte and Harry (Evan Handler) York-Greenblatt have a little run-in with “‘Til death do us part.”

While waiting for a table for their romantic dinner, Charlotte complains about her ungrateful children.

Lily (Cathy Ang), who got broken up with two weeks before Valentine’s, was terribly ungrateful about Charlotte letting her have an “F the boys” party — complete with Taylor Swift’s “Anti-Hero” blaring in the background.

Rock (Alexa Swinton), with whom Charlotte scoured the city in search of a top modeling agency after the success of their Calvin Klein ad, suddenly decided they’re no longer interested (They even accuse Charlotte of having “Dance Mom vibes”).

Charlotte works herself up until she thinks she’s having a stroke. “I can feel my blood!” she shrieks to Harry.

But as an ER doctor soon informs her, it turns out that the brownie she snagged from Lily’s party earlier was a little more Mary Jane than Betty Crocker.

Super high and feeling low, Charlotte realizes it’s time to do something for herself, and determines to take Mark Casabian (Victor Garber) up on his job offer at an art gallery from a few episodes back.

This week also features a fun cameo from Drew Barrymore, who hosts Anthony Marantino’s (Mario Cantone) “Hot Fellas” bread delivery service on her talk show.

Finally, Lisa Todd Wexley (Nicole Ari Parker) declares war on son Henry’s girlfriend Baxter. Baxter is a little too PDA-obsessed for LTW, who decides to set a “booty trap” before leaving the teens alone in her apartment, so she’ll be able to tell if they have sex in her bed.

The bed is meticulous when she and husband Herbert (Christopher Jackson) return from dinner, but something isn’t quite right. Lisa finds Baxter posing with her über expensive handbags — a capital offense for those fluent in Hermès.

“Sex, that’s one thing,” Henry’s dad scolds him. “But your mother’s closet? Have you lost your mind?”

Lisa found a husband who understands that it’s better to mess with the bed than the Birkin, and that’s a happily ever after if we’ve ever heard one.
