It's the final stretch!

Jenna Jameson, who is expecting her third child and first with fiancé Lior Bitton, is showing off her burgeoning baby bump on social media.

The former adult star, model, and reality star took to Instagram to share a photo of her 27-week pregnant belly.

"27 weeks pregnant and feeling amazing," the 42-year-old star wrote. "Just finished my glucose test and now I'm in the home stretch! I can't wait to meet this little one, my little star!"

The star is already mom to twins Jesse and Journey, 7, and is set to welcome her third in just a couple short months.

In the weeks leading up to her due date, Jenna has already noticed the differences in this second pregnancy.

"Crazy how big I've gotten so quickly… my doctor says it's because I previously had twins," she previously wrote. "Oh well! I'm getting the full pregnancy experience this time!"

We can't wait to meet the little one!
