All Kate, all the time!

Kate Gosselin has scored yet another TV engagement.

On Wednesday, the 35 year-old will be a special co-host on Entertainment Tonight alongside Mary Hart. Her ex Jon Gosselin has appeared on ET's sister show The Insider.

In addition to her current stint on Dancing with the Stars, the single mother of eight -- who appeared on The View last year -- will headline her own TLC series Twist of Kate, airing this summer. Her kids will also be returning to the small screen in a series of specials on the cable network. "They're very excited," she said last week.

But the busy Hollywood newcomer bristles at her ex-husband's charge that she has chosen fame over her children.

"I would rather be at home with [my kids]," she said on the Today Show Tuesday. "But I have to work. I have to provide for them. It's a struggle every single mom goes through."
