Reality TV dad Jon Gosselin was spotted playing with his kids on father's day -- and wife Kate was notably absent.
Jon, the twins and the 6-year-old sextuplets were spotted playing with slip and slide toys and the family dogs in front of the garage on their sprawling 24-acre estate in Wernersville, Pa., on Sunday, according to Entertainment Tonight.
Mom Kate was not seen in the photos.
Not even Jon appeared to know the whereabouts of his wife.
"I have no idea," he said today, according to Usmagazine.com.
The two spent their 10th anniversary apart from one another and said they will announce a "life-changing decision" on the next episode of "Jon & Kate Plus 8" Monday night -- fueling speculation that the two are on a one-way trip to splitsville.
"Recently, we've made some life-changing decisions," Kate said in a video statement. "Ones that we hope will bring each of us some peace."
Tabloid headlines have been dominated by the couple's rumors of infidelity for months. Jon has been linked to a 23-year-old school teacher and reportedly ditched Kate on her birthday to spend time half-way across the country with his new gal pal.
Kate was accused of having a tryst with her bodyguard. Both have denied the rumors.
"Very swiftly we turned into two different people," Kate said during the show's premiere last month. "It's just hard."
Jon said he hasn't seen his gal pal as often as he used to, Usmagazine.com reported.
"Not as much with the events that went down," he said.
The father of eight who was photographed smoking last week also said he hides his habit from the children.
"I don't smoke in front of the kids," he said.
