The singer and husband Jay-Z - whose real name is Shawn Carter - welcomed their first child into the world last month and the 'Crazy In Love' hitmaker's mother Tina Knowles is loving being a grandmother to little Blue Ivy Carter.
Tina said: "She's doing great. She's beautiful.
"[Being a grandma is] amazing. It's the second best job I've ever had."
While Tina is smitten with the baby, she is unsure just yet as to which of her famous parents the tot resembles.
She added to People: "She's only a month old. So we have to give her a minute."
Meanwhile, it has been revealed that Beyonce and Jay-Z's close friends Gwyneth Paltrow and Chris Martin splashed out on a $1,029 black Bugaboo Chameleon stroller for Blue Ivy.
A source told Life & Style magazine: "It only makes sense for Beyonce to have this ultrachic stroller. Blue has the hottest ride!"
Blue isn't the only person to be given gifts since her birth - Beyonce's manager splashed out $9,500 on two pendants for the 30-year-old star.
A source said: "Her manager ordered Tacori monogram B pendants for Beyonce."
According to the insider, one pendant features blue sapphires in tribute to Blue Ivy, while the other is a diamond letter B.
