Kate Gosselin's 13-year-old twins, Cara and Mady, became tongue-tied Thursday morning on "Today," as co-anchor Savannah Guthrie interviewed the former reality-TV star and the eldest of the eight Gosselin children.

"Mady, what would you want to say about how you and your sister and your family are doing?" Guthrie asked. Mady, smiling nervously, said only, "Umm!"

"Mady, your words," said Gosselin, 38, who had starred with former husband Jon on TLC's "Jon & Kate Plus 8," about the family of twins and sextuplets. "It's your chance. Spit it out."

When neither teen responded, Gosselin explained, "So this is their chance to talk and this is the most wordless I've heard them all morning. I don't want to speak for them, but, Mady, go ahead," she urged her daughter, suggesting points made in a recent People magazine profile, "that years later they're good, they're fine. Go for it, Mad."

"No," Mady replied, "you just said it."

The teen became more expansive when Guthrie asked Cara, who remained silent, if she thought people had the wrong impression of their family. "I wouldn't say wrong," Mady replied for her sister. "I would just say not, like, the full story. Like, a lot of people, like, think that filming our show has damaged us, but it's only really helped, not really done damage."

And ultimately, when Guthrie asked the girls if they'd like to do another reality show, Mady answered eagerly, "Yeah!"

Tweeting after the show, Gosselin blamed the girls' reactions on "stage fright."
