The 'Shake It Off' hitmaker revealed the sad news earlier today (09.04.15) that her mom Andrea is battling cancer and the 'Sin City' star has offered her best wishes to the Swift family in light of recent events.

She wrote on Twitter: "#PrayForMamaSwift We love you Taylor, Austin, mama and daddy Swift. (sic)"

Mindy Kayling took to the microblogging site to offer her sympathy to the star, writing: "@taylorswift13 stay strong. Love to your Mom. (sic)"

Whilst singer Shawn Mendes simply wrote, "#PrayForMamaSwift (sic)," alongside a love heart.

Fans have also been offering their support to the 25-year-old singer and her family, with one writing: "I hope mama swift knows how big her extended family is and how much we love her. Every single one of us will be praying for her. (sic)."

Another added: "@taylorswift13 our thoughts and prayers are always with you and your family. Hope Mom Andrea gets better & recover soon. (sic)"

The tragic news was announced by the 'Blank Space' singer through a post on her Tumblr.

She wrote: "For Christmas this year, I asked my mom that one of her gifts to me be her going to the doctor to get screened for any health issues, just to ease some worries of mine. She agreed, and went in to get checked. There were no red flags and she felt perfectly fine, but she did it just to get me and my brother off her case about it.

"The results came in, and I'm saddened to tell you that my mom has been diagnosed with cancer."
