The "Motivation" songstress and judge on the British version of X-Factor was spotted looking lovely outside the BBC Radio 1 studios in London.
The 30-year-old singer has recently just won the Ultimate TV Personality prize at the Cosmopolitan Ultimate Women of the Year Awards 2011 in London. With all this going on, she's a bit confused at what to get Beyoncé for her baby shower gift!
She told BANG Showbiz:
"I'm so happy for my sister and her husband. They're so happy in this moment right now, as they should be. They've made a little bundle of love, I'm so excited for them.
"I have no idea what I'm going to buy Beyonce at the baby shower because Jay is going to buy that little girl every single thing possible. She won't be spoiled but she will be very well looked-after.
"I'll be on hand for babysitting duties and I'm actually very good with messy diapers!"
Congratulations to Kelly on the continuing success, but we wonder what Bey will think about Kelly spilling the beans!
