Taylor Swift is Diet Coke's new golden girl!

The 23-year-old country songstress released the above video ... announcing to the world that she has partnered up with the soda giant.

The "We Are Never Getting Back Together" singer says:

“I wanted to share some news with you, because we’re finally making it official with one of the great loves of my life…Diet Coke."

For a second there, we thought she was gonna say Harry Styles. Bummer! As for the Diet Coke deal, Swift will be the focus of the brand's Stay Extraordinary Campaign.

The dollar figure for the partnership hasn't been revealed, but many speculate it's in the seven-figure range. Taylor adds:

“I’ve said for years that Diet Coke just ‘gets me’ and my lifestyle. I’m so excited about our new partnership."

Sweet deal, indeed!

She's looking great!

Taylor Swift made sure to turn heads on the red carpet while avoiding an awkward moment Saturday in her sexy gold gown (and matching heels) when she attended the NRJ Music Awards at Palais des Festivals in Cannes, France.

The 23-year-old singer managed to avoid an awkward moment with her ex Harry Styles and his band One Direction, who were also in attendance, but also got to enjoy a bit of sweet revenge as she performed her hit We Are Never Ever Getting Back Together for him and the world to witness.

Talk about letting the world know where you stand!

Taylor Swift apparently can't live without her ex Harry Styles!

The 23-year-old country cutie arrived in Nice, France for the Cannes Film Festival, and she's staying at the same hotel as One Direction. Using lyrics from her recent hit, sounds like "trouble, trouble, trouble!"

Wearing a crisp white shirt, skinny jeans and riding boots, the "We Are Never Getting Back Together" songstress looks like she's planning to stay awhile.

Perhaps these two will reignite their flame in the City of Light!

Wow ... Taylor Swift is workin' that sexy body of hers!

The 23-year-old country songstress walked the blue carpet at the 40 Principales Awards in Madrid looking gorgeous in a white Kaufman Franco dress and Christian Louboutins.

Swift took home the award for Best International Artist. She Tweeted:

"Tonight was my first time at the 40 Principales Awards in Madrid and it was amazing. Thanks to the fans for the International Artist Award."

Taylor was fun and flirty in short tap pants and a red sequined top for her performance. Harry Styles MUST be missing this!

Taylor Swift makes the perfect Rapunzel!

The country cutie is the latest starlet to take part in a print campaign for Disney Parks shot by famed photographer Annie Leibovitz.

Swift is sporting long blonde hair in the photo which was shot in Culver City last June. Bummer ... we were hoping she was actually sitting in a real castle!

Poor girl is still waiting for Prince Charming to arrive. So much for the fairy tale.

Taylor Swift went under the knife "back in April" to get her breasts enhanced, according to In Touch.

While walking the red carpet at the Golden Globes, the 23-year-old country cutie showed off a very curvy body in a backless Donna Karen Atelier gown.

The gossip magazine claims Swift went from a size A to a B cup.

Check out the below photo of Taylor from the 2008 American Music Awards showing less ample assets. Taylor's rep has yet to issue a response to the boob job claims.

She looks great, but not as good as she did in that stunning white Ralph Lauren dress at the People's Choice Awards the other night!

Taylor Swift struck a pose at the 70th annual Golden Globe Awards at the Beverly Hilton Hotel on Sunday, and she wore a Donna Karan Atelier dress, Lorraine Schwartz jewelry, Rene Caovilla shoes, and an Oroton clutch.

Taylor was nominated tonight for Best Original Song for “Safe and Sound” from The Hunger Games soundtrack, but she lost out to Adele, whose tune for "Skyfall" took home the prize. Better luck at the Grammys, perhaps?

Looks like it's time to face the music!

Taylor Swift got back to what she knows best as she and her trusty guitar took a trip to Conway Studios in Hollywood on Thursday.

The 23-year-old singer has been mum since split rumors between her and One Direction's Harry Styles surfaced earlier this week. Could she be crafting a tune about her pop star ex?

All signs point to YES!

"Back in the studio. Uh oh..." she tweeted Thursday.

That sounds like a definite warning for her former British beau!
