Next to a gorgeous pic of son Bodhi kissing her growing baby bump, and hubby Mark Webber in the background, the Point Break actress writes: “And just like that my heart grew bigger ❤️✨ Welcoming baby number 2 in to the family. Can’t believe our little Bodhi is going to be a big brother!”.
“Thank you for all the sweetest messages and well wishes on our new little one,” Teresa later writes.
“Cried reading all of your beautiful comments. Means so much to us.”
Mark, who has a son Isaac from a previous relationship, also shared the big news on Instagram with a beautiful pic of Teresa in the sea.
“There’s a baby in there. ❤️”, posts the proud dad.
The pair first started dating in September 2012 and got married in December 2013 in Mexico, just three months after announcing their engagement and that they were expecting a child together.
In 2014, Teresa and Mark tied the knot again, this time legally, in a Christian ceremony in California.
Other Aussie stars were quick to join the celebrations on social media.
“More boys!!! Yay!!!, writes Lara Bingle.
It’s a big week on the home and work front for Teresa, 30.
On June 1, 2016, she’s due to launch Your Zen Mama, a sister site to her popular lifestyle portal Your Zen Life.
Your Zen Mama aims to be a community for “Mamas, Papas and Caregivers to feel empowered, inspired, accepted and supported”.
