Taylor Swift Sits on Tom Hiddleston's Lap in Cutest PDA Pic Yet -- See All the Crazy Fourth of July Pics!

The 'Blank Space' singer hosted pregnant Blake Lively, Gigi Hadid and plenty more famous friends for a weekend of PDA and selfies.

This is the PDA picture Taylor Swift has been dreaming of her whole life!!!

The "Blank Space" singer sits on the lap of her boyfriend, Tom Hiddleston -- who, unfortunately, packed clothes other than the "I [Heart] T.S." tank top -- while Ryan Reynolds cradles Blake Lively's pregnant belly one porch chair over. Thank you for posting this, not just for us but for Taylor Swift, Britany Maack.

(Who? Britany is Taylor's childhood friend. Taylor was the maid of honor at her wedding earlier this year and brought along a Vogue reporter. Britany and her new husband, Ben LaManna, are that other couple in the picture.)

Taylor herself has yet to post any pics with Tom from the weekend, instead opting for gIrL pOwEr and posting a billion of shots of her famous friends, including Blake, Ruby Rose, the Haim sisters and more!

Here's model Gigi Hadid, model Cara Delevigne and Taylor -- who performed at the Victoria's Secret fashion show, so, sure, she can be a model too -- fulfilling their patriotic duty of posing with a flag in a red, white and blue swimsuits.

Here is a picture of Taylor and Cara walking, which doubles as a real estate brag.

Also, who took this?

There was a giant water slide at the party too! And Karlie Kloss was there!

And singer Rachel Platten! (Credits: "Fight Song.")

And actress Kennedy Rayé! (Credits: Snapchat.)

Martha Hunt made a polaroid collage featuring the second cameo by Tom Hiddleston. (In the top left corner! There he is!)

And here's one of those Haim sisters being a real prankster!

Here's Taylor with another one of her childhood best friends, Abigail Anderson. A few notes: Taylor's temporary tattoo is the same one Tom chose to wear or was told to wear that same day. Secondly, the theme of the party was maybe honestly "Taymerica"

Here is an Anthropologie ad.

Here is a game night action shot, where we would guess that, based on body language and the general sense of atmosphere, they are playing charades or celebrity. (Do celebrities play celebrity?)

More people on the guest list: Cara's girlfriend, St. Vincent (above), and Ruby Rose's girlfriend, Harley Gusman (below, in a fireside photo where everyone looks cute and casual and Taylor is full-on posing.)

And here is Ruby kissing Harley, because Rhode Island is the most romantic of all the states, have you even been paying attention to Taylor and Tom's love story?

Welcome to the land of the free and the home of brave! Taymerica, we salute you!
