The whole world is already in love with Beyoncé's twins, including LeToya Luckett.

ET's Kevin Frazier caught up with the singer on the red carpet at the BET Awards on Sunday, and she had nothing but love for her former Destiny's Child bandmate's new babies.

While she admits she hasn't had the chance to see them yet, she has no doubt that they have the "cutest, chubbiest cheeks."

As for the new mom herself, Luckett explained that she's been in contact with Beyoncé's mom, Tina Knowles, who had good news about her daughter and the twins.

"I did run into Ms. Tina and she says they are doing just fine," Luckett shared.

The 36-year-old singer
also opened up about the recent success of her ex-boyfriend, Golden State Warriors star Kevin Durant, who helped his team take home the NBA championship after defeating the Cleveland Cavaliers earlier this month.

"I'm excited for my friend for that championship and to win it and take that thing. I'm so excited for him," she said. "We prayed together about it several times. When you see your homie win like that you're literally in tears watching. I was so happy for him. I'm happy for him and his family and that's awesome."

Luckett wasn't Durant's only ex who was rooting him on during the NBA Finals. Rumored former flame and current Bachelorette Rachel Lindsay was also spotted in the crowd during Game 5. However, Luckett said she didn't have any interest in Durant's personal life.

"I don't know nothing about that," she said, referring to rumors that Lindsay and Durant had once been an item. "I ain't got nothing to say about that, but yeah, good luck to them both."

In May, Luckett sat down for a Facebook Live with ET where she opened up about her experiences as part of the mega-popular girl group Destiny's Child.

"I think the beautiful thing about DC is none of us came into this to use it as a platform to go solo," she shared. "We were just four girls who wanted to sing. That's it. I think the best thing that you can do is be a team player and play your role."
