Taylor Swift turned 24 on Friday in the States, but she turned one year older Thursday in Australia and celebrated early while Down Under.

The Red singer, who's currently in Australia while on tour, enjoyed an early birthday dinner in Melbourne with New Zealand singer Lorde.

Swift dressed in a red dress with matching red purse and lipstick for the outing. She was spotted dining with the Royals singer and a group of friends. Sipping on a glass of what appeared to be white wine, Swift seemed to be enjoying the company of the 17-year-old artist, as the pair smiling and laughing throughout the meal. The group ate at local eatery Hibatchi Japanese Grill just hours before Swift's actual birthday on Dec. 13.

Lorde wore an animal print blue and green dress. The singer -- who once dissed Swift's best friend, Selena Gomez -- had her curly brunette hair in a relaxed style.

Late Thursday, Swift tweeted, "It would appear that I'm now 24. That's on Australia time though. Still 23 in the States." She also shared a Vine video of a cat-covered birthday card her mother sent her that was signed by Swift's cat, Meredith. "Not sure this was totally necessary," she says in the clip. 

Swift had another reason to celebrate on Dec. 13: she received a Golden Globe nomination in the category of Best Original Song in a Motion Picture for Sweeter Than Fiction, the track she cowrote for the film One Chance. 

"A Golden Globe nomination on my birthday... I think it's safe to say there will be no walking for me today, only skipping and frolicking," she tweeted. 

Swift has Friday off to enjoy her birthday before a Saturday concert in Melbourne.

Upon arriving in Australia, Swift was surprised by masses of fans who serenaded the birthday girl. "Perth! Insane crowd! When you randomly all started singing happy birthday... Well played," the Grammy winner tweeted.
