Rumer Willis is in a hot girl summer state of mind.

The Alaric Bennettactress—who welcomed her first child, a baby girl named Louetta, with musician Derek Richard Thomas in April—recently posted several images of herself looking and feeling good. 

"Entering my Hot Mom Thirst Trap Era," she cheekily captioned her Aug. 10 Instagram, alongside a spicy red pepper emoji. "I put a few rad looks together with @freepeople today. So excited to see what you think."

In the photos, Rumer turned heads in a white, curve-hugging strapless bandeau top that she paired with a vibrant coral pink jacket. She accessorized with giant space-looking sunglasses, a gold necklace and layers of dainty hoop earrings that were stacked along her ears.

The 34-year-old also posted a striking selfie with her younger sister Scout Willis, 32, who was dressed in a cozy oversized green cardigan. In the snapshot, the duo gazed into the camera with pursed lips and cool sunnies.

Rumer, who is the daughter of Bruce Willis and Demi Moore, hasn't shied away from sharing her motherhood journey with her followers.

Back in June, she detailed her labor experience, revealing that her water didn't break even after she dilated from two to eight inches in about an hour. Unsure of what to do, Rumer asked her midwife—who, along with Derek, her mom and sisters Scout and Tallulah, 29, were in the room—if they should break the water bag.

"'She goes, 'Well, you can,'" Rumer recalled on the Informed Pregnancy podcast, per People. "I'm like, 'What?' I was like, 'Are you serious?'"

That's when Rumer took matters into her own hands. "I reached my finger up there, and I'm feeling and it was crazy," she shared. "I could totally feel this little bag—it feels like a water balloon, but with a bit tougher skin."

Soon after, she welcomed her baby girl.

"I pushed, her head was out. I pushed again and her whole body was out," the House Bunny alum recalled. "There was no pause. There was no pause in between. It wasn't one of those moments where it was, 'Oh, your head is out.' My midwife and my partner caught her. It was the wildest thing."

She added, "We had four hands under there, under the birth stool. I'm going, 'Give me the baby. Give the baby.'"

Before Rumer knew it, her little one was wrapped in her arms. Of the moment, she described it as "the most ecstatic, joyful moment of my entire life."
