The latest milestone for Jon and Kate Gosselin's eight kids? Meeting their dad's new girlfriend.
On Saturday, Jon Gosselin hit a playground in Wyomissing, Penn. with his 9-year-old twin daughters Mady and Cara and 6-year-old sextuplets Alexis, Hannah, Aaden, Collin, Leah and Joel. Joining the kids as they played on the swings and monkey bars: Ellen Ross, 23, his girlfriend of one month.
"She is the first love interest to be introduced to his children," a source close to Jon, 33, tells Us of Ross, who lives in nearby Harrisburg, Penn. Gosselin recently moved into a one-bedroom apartment in Reading, Penn., to be closer to the Wernersville, Penn. house the kids share with his ex-wife Kate.
Although the kids were "confused" meeting Ross a few days earlier, a source says the famous kids "really taken to Ellen and she's enjoying spending time with them."
Back in March, the reality dad (whose prior ex-girlfriends include Hailey Glassman and Deanna Hummel) was dumped by Morgan Christie, his 25-year-old girlfriend, after less than two months. He was subsequently linked to a wealthy "fortysomething" woman from Washington, D.C.
