Taylor Swift Gets a Visit From Jay Z and Justin Timberlake at Home—Please Say They Baked Cookies!

We like to think they all talked music, had a rap battle and did some holiday-themed craft-working during their brief visit

Are we looking at Taylor Swift's latest partners in musical collaboration?

Or better yet, the latest two BFFs to bake cookies at the pop super-star's Manhattan pad? What would be better than a makeshift holiday crafts party featuring Jay Z and Justin Timberlake? (Aside from a makeshift holiday crafts party that also featured a rap battle, that is.)

After the trio all partied together over the weekend for Taylor's 25th birthday, the revered "Suit & Tie" duo paid a visit to Swift's apartment this afternoon...

And we've been refreshing her Instagram page for pictorial evidence of what they were up to ever since!

But in the meantime, both Jay Z and Justin were spotted leaving together, and Taylor—accompanied by a bunch of luggage—was photographed exiting the building a short time later.

After launching her birthday festivities with a ladies' night dinner on Thursday, Taylor went on to enjoy a "Happy Birthday" serenade from Aretha Franklin at the Billboard Women in Music luncheon on Friday; then, she partied into the night with Jay Z and Beyoncé, Timberlake and so many more of her famous friends after performing at iHeartRadio's Jingle Ball 2014.

Selena Gomez, Karlie Kloss, Sam Smith, Iggy Azalea, Jaime King, Nick Jonas, Olivia Culpo were among those who made the scene.

Jay Z also worked the turntables at the b-day party, according to longtime Swift bestie Abigail Anderson. "@taylorswift knows how to throw a birthday party. Happy 25th my O.G. Bestie," Abigail captioned one of several Instagram montages.

"What an incredible weekend with incredible people," she added. "See you next time New York. #JayZwastheDJ#imnotevenkidding #heactuallywas."

"When you're making a wish, but you already have all you really need standing around you," Taylor Instagrammed a pic of the birthday-cake portion of the evening, the star in a plaid crop top and pants and standing in front of a dressed-to-the-nines Christmas tree.

The cake was a signature confection from Momofuku Milk Bar, available to anyone with $100 and a hearty sweet tooth.

"Think everyone's favorite childhood cake reswizzled milk bar style- vanilla rainbow cake layered with rainbow cake crumble & vanilla frosting!" a rep for the NYC bakery and sweet shop told E! News.

And no, this core group did not get tired of each other.

Last night, Taylor shimmied alongside Beyoncé and the Grammy-nominated sisters of Haim at J.T.'s concert at Madison Square Garden—which was also attended by Timberlake's reportedly pregnant wife, Jessica Biel.
