The 'Lover' hitmaker feels "so lucky" to have marked her milestone birthday with some of her closest friends - including Ryan Reynolds, Blake Lively, Jack Antonoff, Martha Hunt and Gigi Hadid - with a festive-themed bash.

She wrote on Instagram: "Honestly spending my 30th with the fans who have made my life what it is at jingle ball, then throwing the most aggressive holiday party known to womankind ... I just seriously feel so lucky for you all and will spend forever trying to find ways to say thank you. *cries in Christmas tree* (sic)"

Taylor previously admitted she is approaching her thirties with a healthier outlook.

Speaking before her birthday, she said: "I'm really excited about it. I've heard really good things about your thirties. Feeling a bit more secure ... a bit."

And Taylor believes her age has helped her to analyse "toxic messages" about her body and improve her relationship with body positivity.

She added: "One thing going into my thirties that I'm really stoked about is I now can really recognise and diagnose toxic messages being sent to me by society, by culture about my body. I'm a woman, I'm not a coat hanger. I need to feel healthy in my life, and I need to take pleasure in food, and I need to not use my body as an exercise of control when I feel out of control in my life."
