Like many in the fashion industry, designer Victoria Beckham is all over social media. She can't get enough of Instagram and its abundance of stylish photos. And as a former Spice Girl and full-time fashion designer who fancies listening to music while working, Beckham pairs her Instagram obsession with a few music apps.

"I always check Instagram, and for music I use Spotify and Pandora," Beckham, who celebrated her 40th birthday in Los Angeles last week, told Mashable.

In a recent interview, we asked her about her fashion brand, who's trendy in tech, and her Skype partnership, aimed at exploring the intersection of the tech and creative industries.

Mashable: Who in the tech world do you think is the most fashionable?

Beckham: There are so many amazing people in the tech world that I admire ... I recently worked with [Facebook chief operating officer] Sheryl Sandberg on the #Banbossy campaign and she is a great ambassador of style for the modern working woman. I also met [Twitter cofounder] Jack Dorsey quite recently and found him incredibly interesting.

You're part of the #BanBossy campaign. In this fast-paced digital world, what is your best advice to girls to help more of them want to become leaders? I often say the best advice is to get as much experience as you can in the field you want to enter. And of course, be passionate and be willing to work hard. I have followed that in my own career and you see that in the Skype Collaboration Project. I hope it encourages women to work hard and follow their dreams.

Why partner with Skype and how have Skype and other video tools enhanced your personal life and work life? I am a working mum of four running a global fashion business, so whether it’s for professional or personal use, Skype connects me with my team and those I need to when we are in different cities. I’m a visual person, and fashion is a visual industry, so the use of video is key. Your e-commerce website launched before your brick-and-mortar retail store — do you think your digital presence is just as important as your offline presence? Yes, I think both are equally important. We chose to launch e-commerce first because we have a global customer base, and the website allows those customers to see the brand through my eyes. VictoriaBeckham.com has been very successful thus far, and has taught us a lot about our clientele. Now we are gearing up to open our first brick-and-mortar retail store in London, and I’m very excited to see our brand come to life in a physical retail space. Online and offline offer different experiences, and I believe the combination of the two is the strongest.

When did you start using social media?

My earliest memory of social media is definitely with Twitter [@VictoriaBeckham, 7 million followers]. It was the first social media platform I joined and I started with it pretty early in 2010. Twitter introduced me to social media as a whole; now I’m on seven different platforms. I love being able to directly communicate with this audience from anywhere in the world.
