Lawson, 63, spoke about the singer’s pregnancy at the Inaugural Wearable Art Gala in Los Angeles on Saturday, opening up about what it feels like to be a grandmother again.
“I’m so excited,” she told reporters. “I can’t wait.”
“She’s a really good mom,” said Lawson. “Really patient and kind.”
Lawson also said that she’s happy to see her daughter handing down the same important messages she tried to instill in her to the next generation of their family.
“Teaching them that what is on the inside counts more than what’s on the outside,” she said. “I see her passing it on, and it makes me really proud because that was my biggest lesson.”

Also during her Extra interview, Lawson revealed she’s currently living in Los Angeles while the parents-to-be are in nesting mode.
“She is surrounded by her family and is taking it easy,” a source previously told PEOPLE exclusively about the Grammy winner. “She doesn’t venture out very much, but seems happy going for an occasional lunch or taking [Blue Ivy] to school.”
The couple is also busy overseeing renovations of their Holmby Hills rental home and have hired decorators for the twins’ nurseries.
“They plan on raising their twins in Los Angeles,” says the source about the previously Manhattan-based pair, who recently vacationed in Bora Bora. “It’s their home base now, and this is where Blue goes to preschool. They’re all very happy in L.A.”
