Apple heiress Eve Jobs unseparated from her iPhone as she joins Bruce Springsteen’s daughter Jessica at an equestrian festival in Florida (Details, pics)

And the 19-year-old heiress, who is the youngest daughter of Steve Jobs, left her phone tucked into her belt as she attended the Winter Equestrian Festival in Wellington, Florida. Her late father founded tech empire Apple, so it's no surprise that Eve Jobs finds it hard to be separated from her iPhone.

Eve looked stylish in a white shirt and matching jodhpurs as she strolled around the arena ahead of Saturday night's show jumping event. She joined 26-year-old Jessica Springsteen, the daughter of Bruce Springsteen, at the festival, with the show jumper looking similarly chic in her equestrian get-up.

Jessica was later seen competing on her horse in the Fidelity Investments Grand Prix CSI 5 on Saturday night. Both women looked completely at home at the Winter Equestrian Festival, which is being held at the Palm Beach International Equestrian Center until the start of April.

Eve, who currently attends Stanford University, is an accomplished equestrian with years of national and international competition experience.

The massive event sees competitors of all ages taking part in a range of disciplines over 12 weeks. At last year's Winter Equestrian Festival, she placed first and second respectively in the Show Jumping Hall of Fame classes during weeks 8 and 9.The previous year, her mother Laurene Powell-Jobs bought a $15million ranch in Wellington where she frequently competes and trains with Missy Clark.

The ranch features four bedrooms, a 40ft long screened-in pool, a detached barn for up to 20 horses, as well as a show-jumping training rink. According to Business Insider, Eve has aced competitions around the world, including events in the Hamptons, Kentucky, Canada and the UK.

Eve is also dating equestrian and Miami School of Business student Eugenio Garza Pérez.
