Taylor Swift has just filed a late contender for best celeb snap of the year, even giving Ellen DeGeneres' famously star-studded Oscars selfie a run for its money.

Take a look at the two-part pic she's posted on Instagram from her 25th birthday party this weekend.

Yes that is Sam Smith standing next to her, and hang on, yes that IS Beyoncé and Jay-Z standing the other side of the mystery man.

And don't start hyperventilating, but the man in the poo mask is the 'real' Justin Timberlake - rather than a tribute act hired for the party.

The HAIM girls are also in the picture, which features party balloons in the background and a variety of novelty festive headgear.

Swifty added the caption: "So this is being 25..... #WHAT #bestbirthdayEVER"

Another snap shows her delightedly blowing out her candles while surrounded by friends in what appears to be her own home.

She wrote: "When you're making a wish, but you already have all you really need standing around you."

And she also showed off her "new most cherished possession", a necklace featuring a forlorn portrait of a cat from Girls creator and star Lena Dunham.
