Taylor Swift savagely trolls Ryan Reynolds and Blake Lively while quietly announcing huge news

We've all know by now how close Taylor Swift is with celebrity power couple Blake Lively and Ryan Reynolds.

But that isn't to say that the trio can't roast each other online, with the chart-topping singer today firing a hilarious round of shots at the Deadpool actor on social media, all the while revealing some pretty exciting news.

For those unfamiliar with how the trio have managed to strike up such a tight friendship over the years, T and B's relationship goes all the way back to 2015.

Three years after marrying Green Lantern co-star Ryan - who she met whilst filming the superhero flick - Blake proved she's been a long-time Swiftie by posting a beauty campaign which seemingly referenced Taylor's newly-released anthem 'Bad Blood'.

In the years that followed, the duo were almost inseparable, often jet-setting around the world together, attending one another's award shows and concerts, with Blake's actor hubby often tagging along.

Remember back in February, during the Superbowl, Ryan and Blake even rocked up to support their friend's new man on the scene - Kansas City Chiefs star Travis Kelce - by cheering for him from the bleachers? Iconic, if you ask me.

Anyway, the trio's bond has strengthened so much over the years, that Taylor, 34, seemingly now feels more than comfortable roasting the couple online.

Taking to Instagram today, the 'Cruel Summer' singer shared a snap alongside Blake, Ryan and Hugh Jackman, to celebrate the latter twosome's work on latest silver screen hit Deadpool & Wolverine, which was released in the UK today.

"Over the past few years I have watched one of my best friends on the planet pour every bit of his heart, soul, sweat, time, energy, jokes, pain, joy, rebellion, darkness and magic into this film," Taylor initially wrote, appearing to be heaping praise onto her BFF's husband Ryan.

"He's created the best work of his life, and this film feels like an actual portrayal of joy, a wild escape from reality, and an abs sandwich."

The hitmaker jokingly continued: "I don't know how he did it - but that's just Hugh for you!

"These other randoms crashed the photo and we were too polite to ask them to leave."

And at the bottom of the post, she included a really heartwarming glimmer of some unknown news.

As we've said, over the years, Taylor has largely become part of the Reynolds-Lively family - especially since the couple welcome their four beautiful children - daughters James, nine, Inez, seven, Betty, four, and 17-month-old toddler Olin.

And in her social media tribute to Ryan's blockbuster efforts, the musician took the opportunity to jestingly reveal that she's actually godmother to the duo's gorgeous youngsters.

Firing one more jibe at the actor by referring his character's name, she added: "Shout out to Wade Wilson, aka my godkids' sperm donor."

Talented, caring and witty. Is there anything this woman can't do?
