Phoebe Tonkin (Hayley) is an aunt! Well, kind of. The Original star’s fellow Aussie actress, bestie Teresa Palmer, gave birth to her first son with director Mark Webber on February 17. And Phoebe couldn’t be happier for her friends. Check out her oh-so-sweet celebratory tweet!

“Couldn't be prouder or more excited for my beautiful friends @likemark and @tez_palmer! Aunty Phoeb will be there ASAP to give him a smooch.x,” Phoebe adorably tweeted yesterday. She is super close to the happy couple. Phoebe was not only present at Teresa’s baby shower, but served as a bridesmaid in their wedding last month: “Bridesmaidin' @tez_palmer @likemark xx miss you both,” Phoebe captioned the Instagram shot she shared of herself with bride Teresa on the happy day.

Teresa and Mark announced the birth to the world via a gorgeous Instagram shot of the baby boy’s hand wrapped around Teresa’s ring finger: “Thank you God for blessing us with the most divine gift of our baby son,” she captioned the black-and-white pic. “Introducing Bodhi Rain Palmer born safely, lovingly and naturally last night. 8lbs even.” She went on to explain the little baby’s somewhat unusual name: “Bodhi means ‘Enlightened one’ Rain means ‘Abundant Blessings From Above’ and we chose Palmer as his last name as Marks son Isaac didn't take his dads name either.”

We wonder if Phoebe’s been getting pregnancy acting tips from Teresa to make her turn as pregnant Hayley on The Originals as realistic as possible. Then again, maybe it’s different carrying the impossible child of a centuries-old supernatural hybrid?

Catch the next episode of The Originals when it returns on Tuesday, February 25 at 8 p.m. ET.
