Victoria Beckham "screamed" when Beyoncé wore one of her dresses.

The "Single Ladies" hitmaker wore a blue fitted design for an event organized by Michelle Obama earlier this week, and mega-fan Victoria admits she was blown away: "She was one hot mama, for sure. I mean, Beyoncé is absolutely beautiful and has the most phenomenal body, she really does. She looks great, she really does. I was very excited when I saw it online. I screamed! I was like, 'Look, David, look!' I still get so, so excited. She's incredible and also an artist that I have so much respect for. I'm a huge, huge Beyoncé fan. It was big for me."

The former Spice Girl balances her fashion line with raising sons Brooklyn, 13, Romeo, nine, Cruz, seven and eight-month-old daughter Harper with husband David - and admits things can get a bit crazy in the Beckham household.

"We were getting ready, trying to feed baby, put the boys in the bath, giving them dinner. Four kids is a lot, a lot more than three. It's great that we have each other because it's definitely a two-person job at all times. People always ask us how we do it. It's no different for us than other people who have careers and children. It's hectic, but we would not have it any other way. We are really, really lucky. With David and with the kids and with my job I'm very appreciative, I really am. Very blessed."
