20110918-014911.jpgAfter hitting New York Fashion Week and sitting front row with sister Solange, Beyonce flew to London to debut her latest House of Dereon collection at London Fashion Week on Saturday.

As the last model stepped off the runway, Beyonce hit the catwalk for a celebratory mommy-daughter moment with her mom (and House of Dereon partner), Tina Knowles.

Clad in a dazzling sequined suit and towering platform heels, Beyonce strutted hand-in-hand with her stylish mom, who also donned a chic, all-black ensemble.

The pregnant star, who wore a cut-out dress in NYC on Tuesday, continues to sex up her mommy-to-be style with a plunging neckline blazer.

The 30-year-old singer and her mom created House of Dereon in 2004. The line of fashions for women is named after Beyonce’s maternal grandmother, Agnez Dereon.
