R&B singer Kelly Rowland took part in celebrating the Australian release of the all-new iPhone 4 early Friday morning (Jul 30) by performing at the Optus Love Lounge at the Town Hall in Sydney, Australia. Once the phone officially went on sale at midnight, Rowland showed off Apple’s new mobile device and posed for press pics at a mobile phone store in the area.

Meanwhile, Kelly revealed in a recent interview that her still untitled third studio album has been delayed until November 2nd, one week later than its original release date of October 26th. Kelly is said to have worked with big names like David Guetta, Ne-Yo, Bangladesh, Akon and more for her new project.
