One more reason the world can't wait to see Blue Ivy Carter:  everyone who's been lucky enough to do so already can't stop gushing about how adorable she is!

In fact, Blue's beauty left Beyonce's bestie Kelly Rowland speechless. "We all just stared at her," Rowland told E! News. "I just stared at her. She is so beautiful."

The U.K. 'X Factor' judge couldn't stop fawning over baby Blue. "She's absolutely beautiful!" Rowland exclaimed. "And I say that with such a huge grin! I'm so excited."

When asked what Blue actually looked like -- besides beautiful -- Rowland replied, "She's just ... She's more precious than a diamond. She's just so stunning. I'm so happy for my sister and her husband. She's beautiful!" she giggled.

Rowland admitted she's going to see baby Blue every chance she gets. "Absolutely," she smiled. "I have to be a good aunt!" She's already begun spoiling little Blue. She was spotted buying presents for the tot, but wouldn't reveal what they were. ""That's between me and Blue," she said. "But you best believe her auntie will have her dressed to impress."

Rowland described Beyonce as "an incredible mother." Aw! "I'm incredibly proud of her," the 'Down for Whatever' singer said. "So proud of her. You know what? She's in Mommyville, and I am so proud of her," Rowland grinned. "And her husband's in Daddyville, and the baby's just very beautiful!"
