Rumer Willis will become a mother.
The 34-year-old actress announced on Tuesday that she and Derek Richard Thomas are expecting their first child.
“🌱,” she captioned three black-and-white images showing off her growing baby bump.
The first and third photos capture the indie musician loving Willis’ pregnant belly, while the second photo shows off her full figure.
Fans and celebrity friends immediately began flooding the star’s post with congratulatory messages.
“I’m so happy for you my friend. Such beautiful news. Congratulations!!!❤️❤️❤️,” Aaron Paul commented, while Brittany Snow noted: “Congratulations beautiful!! ❤️❤️😍”.
Willis’ supportive sisters were not far behind.
“I feel so good. What a fun rocking launch party!” Scout Willis, 31, wrote, while Tallulah Willis, 28, exclaimed: “EEEEEEEE!!!! we stand up to this mom!!”
Mother-of-three Demi Moore, 60, chose to re-share the three snaps and cheekily captioned them: “Entering my hot unattached grandma era 🌱.”
Rumer only recently confirmed her relationship with the Vista Kicks frontman, posting sweet photos of the happy couple posing against a fall backdrop last month.
While it’s unclear when they started dating, Thomas gushed over the “House Bunny” star at a birthday party in August.
“In the short time we’ve been together, you’ve filled my life with joy and peace,” she captioned an Instagram photo of the duo “cramming at the Stones in London.”
He added: “Everything is very easy with you. We sing, dance, play and most of all laugh. Thank you for being you 😘 you are a magical person. I am so happy that you came into my life.”
Rumer first hinted at their romance in May when she referred to Thomas as “one of the most talented singers and songwriters I’ve heard in a very long time (maybe ever).”
News of the Dancing With the Stars star’s pregnancy comes nine months after her father Bruce Willis, 67, announced his retirement from acting after being diagnosed with aphasia.
