Solange Knowles can't wait to meet her sister Beyonce Knowles' baby.

The former Destiny's Child star and her husband Jay-Z are expecting their first child together and singer Solange can barely contain her excitement about the tot, who is due in February.

The 25-year-old star - who has a seven-year-old son Julez with her ex-husband Daniel Smith - told Us Weekly magazine: "My sister is a phenomenal aunt, so I'm ready to be the same in her life. I don't need any advice [on how to be a great aunt]. Because she has been a phenomenal aunt to my son, so she's set the tone as an aunt. I've set the tone as a mom, so we're learning from each other."

Solange is confident she will be able to match 30-year-old Beyonce in the aunt stakes, but she knows she has a lot to live up, because her sister loves to spoil Julez.

She added: "Well, I'm sure my son would say she's the better aunt because I'm a mom first. I do realise that popcorn at 9.00 at night probably would make me the better aunt."
