The 'Real Housewives of Beverly Hills' alum exclusively tells PEOPLE on Friday, Nov. 15, that her daughter is growing her family again

Lisa Vanderpump's eldest child, Pandora Sabo, is expecting her second child with husband Jason Sabo.

The former Real Housewives of Beverly Hills star, husband Ken Todd, daughter and son-in-law all attended the red carpet at the Vanderpump Dogs Gala at the Maybourne Beverly Hills on Friday, Sept. 15. Pandora and Jason, both 38, posed for photos with their son, Teddy, 3.

Pandora gestured towards her baby bump as Jason smiled on.

Lisa, 64, exclusively confirmed to PEOPLE that her daughter is expecting her second child. "She hasn't announced it yet but tonight it's pretty obvious. Yeah, we are expecting our second grandchild, so it's very exciting."

While the Vanderpump Rules star says she knows the grandchild's sex, she remained tight-lipped about further details.

Pandora and Sabo, who tied the knot in 2011, announced the birth of their first child, Teddy, in November 2021.

"Theodore. 6lb 7oz of pure delicious joy. Your entrance into this world was the best day of our entire lives and your daddy and I are so thankful that you are here, healthy and happy," Pandora wrote in the Instagram caption. "You are so loved little Teddy!"

"Theodore. You are my everything, I love you so much, thank you for making me a mummy!" she captioned another photo.

Before the reality TV star became a grandmother, she told PEOPLE how excited she was to welcome the little one. "It's a blessing. I love children, I love being a mother ... it's such welcome news for us,” she said in August 2021.

After Teddy's arrival, Lisa also celebrated with a heartfelt message. "Obsessively in love with baby Theodore. Thank you Pandy and Jason for making me a Nanny Pinky,” she captioned an Instagram picture of herself holding her grandson.

Since Teddy's birth, Lisa has shared various photos of her grandson, including major milestones such as his christening. The TV personality also provided peeks at his first Halloween, when he was dressed as an adorable pirate and his first birthday.

More recently, ahead of his third birthday, Lisa shared sweet photos alongside the toddler as he helped her blow out her birthday. On Monday, Sept. 16, she posted an adorable photo on her Instagram with Teddy in her lap and smiled as his grandma leaned in over an ice cream dish.

"It's been extraordinary," Vanderpump described her experience as a grandmother. "I absolutely love being a mother. They get to [age] 18 and then take off, and then to have that whole experience again, it's wonderful."

Vanderpump remains equally inspired by dogs. "We take on causes that other people don't, so that becomes very expensive," she said of the Vanderpump Dog Foundation. "We keep every dog. Sometimes we have a dog in the shelter for a long time, but to us, they're all adoptable and we hope to find them their forever home."
