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

Pandora gestured to her baby bump as Jason continued to smile.

Lisa, 64, confirmed exclusively to PEOPLE that her daughter is expecting her second child. “She hasn’t announced it yet but tonight it’s pretty obvious. Yes, we’re expecting our second grandchild, so it’s very exciting.”

While Vanderpump Rules star says she knows the grandchild’s gender, she was 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 entry into this world was the best day of our entire lives and your dad and I are so thankful you are here, healthy and happy,” Pandora wrote in the caption on Instagram. “You are so loved little Teddy!”

“Theodore. You are my everything, I love you so much, thank you for making me a mother!” she texted another photo.

Before the reality TV star became a grandmother, she told PEOPLE how excited she was to welcome the little one. “It is 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 Nanny Pinky,” she wrote a Instagram picture of himself holding his grandson.

Since Teddy’s birth, Lisa has shared various photos of her grandson, including big milestones like his baptism. The TV personality also gave looks at his first Halloween, when he was dressed as an adorable pirate and his first birthday.

More recently, on the eve of his third birthday, Lisa shared sweet pictures together with the little one when he helped her blow out her birthday. On Monday, September 16, she posted an adorable photo of her Instagram with Teddy on his lap and smiled as his grandmother leaned in over a bowl of ice cream.

“It’s been extraordinary,” Vanderpump described her experience as a grandmother. “I absolutely love being a mom. They get to (age) 18 and then take off, and then to have that whole experience again, it’s wonderful.”

Vanderpump remains just as inspired by dogs. “We take on things that other people don’t, so it gets very expensive,” she said Vanderpump Dog Foundation. “We keep all the dogs. Sometimes we have a dog in the shelter for a long time, but to us they are all adoptable and we hope to find them their forever homes.”
