Taylor Swift’s high school BFF, Abigail Anderson, announced that both she and husband, Charles Berard, have welcomed their first child together on Instagram on Friday.

The media personality, 34 – who revealed her pregnancy last month using a quote from one of the Grammy winner’s songs – has known Swift, also 34, since they were 15-years-old.

Anderson – who tied the knot with the chief technology officer at Celero Commerce in 2022 – shared a black and white photo of their baby boy’s tiny fingers wrapped around her own.

In the caption of the post, she typed out to her 483k fans and followers, ‘Baby boy decided to join us a few weeks earlier than expected.’

‘Our hearts are exploding with love. Welcome to the world Bennett, it’s entirely yours,’ Abigail added, followed by a blue heart emoji.

Social media users jumped to the comment section to share their congratulations to Anderson and her husband over the exciting news.

Supermodel Lily Aldridge wrote, ‘Sending so much love & congratulations ❤️❤️❤️❤️❤️❤️❤️.’

One fan used lyrics from Swift’s 2010 track, Never Grow Up, and penned, ‘”Your little hand’s wrapped around my finger, and it’s so quiet in the world tonight.”‘

Last month in July, Abigail announced that she was expecting baby number one with her husband, Charles.

At the time, she uploaded a photo of herself enjoying a box of Cheez-It crackers and showed off her growing baby bump in a black blouse that was partially unbuttoned at the front.

‘I’m having his babyyyy…,’ she added in the caption of the image, followed by a blue heart emoji.

Anderson referenced to lyrics from Taylor’s song, Daddy I Love Him, from The Tortured Poets Department album that dropped earlier this year in April.

In the track, the performer could be heard singing, ‘Now I’m running with my dress unbuttoned/Screaming “But Daddy I love him!”/I’m having his baby/No, I’m not, but you should see your faces.’

Abigail said ‘I do’ to Berard in October 2022 and uploaded pictures to social media at the time as she flashed a cheerful smile in a white gown with her husband.

Swift and Anderson have been best friends since meeting in high school when they were 15-years-old.

Her close friend also inspired Taylor’s song, Fifteen – which is found on her Fearless album (2008).

Lyrics in the track include: ‘You sit in class next to a red-head named Abigail/And soon enough you’re best friends/Laughing at the other girls/Who think they’re so cool/We’ll be out of here as soon as we can.’

Abigail has also made cameos in various music videos of Taylor’s, such as Fifteen and Picture To Burn (2008).

During an interview on The Oprah Winfrey Show in 2009, the Bad Blood songstress opened up about her friendship with Anderson.

‘But my best friend, Abigail, we met when I was 15. First day of school freshman year, we sat next to each other in English.’

Taylor also recalled, ‘She wanted to be a swimmer and go off on a college scholarship for swimming and I wanted to be a singer. Now she’s off at Kansas on a swimming scholarship and I’m singing.’

Swift and Anderson have also appeared on each other’s social media pages over the years.

Late last year in December, the award-winning music artist took to Instagram to share an assortment of memorable snaps from her 34th birthday bash.

In one of the group photos uploaded to the post, Abigail could be seen flashing a big smile as she stood behind Taylor and Blake Lively.

Swift’s BFF also appears to support the star’s romance with the Kansas City Chiefs tight end, Travis Kelce.

In November of last year, she liked an Instagram post shared by E! News that showed a clip of Taylor changing her lyrics to Karma to mention Kelce.

The songstress returned to the stage at Wembley Stadium on Thursday following the Vienna terror plot and tragic Southport stabbing in the U.K.

She is set to perform four additional dates at Wembley beginning on Friday and will conclude on August 20.

The star will travel back to the United States to perform in cities such as Miami and New Orleans beginning in October.

The Eras Tour – which kicked off last year in March – will come to an end with concerts in both Toronto and Vancouver. The final date is slated for December 8.
