Looking vibrant in a bright yellow dress and hot pink hair, Katy Perry made a colorful appearance on The Ellen DeGeneres Show, where she opened up on babies and announced plans for an upcoming FREE concert!

The "Firework" singer, who celebrated her 1-year anniversary with hubby Russell Brand last month, talked about starting a family:

    "Yeah, I would love to have children. I think that's one of the reasons you get married. Especially to the person that you marry. You think, that person is going to be a good partner, a good parent. But, I'm not sure it's yet. We'll see, ya know ... If it doesn't hurt the first time, I'll keep popping them out."

Let's hope Russell's cool with that!

Perry went on to announce a surprise free concert in LA for fans:

    "It is the 23rd of November. The day before Thanksgiving. I am giving thanks to all of my fans. This is my big announcement on 'Ellen' that no one has heard about or knows about. I played a 121 shows up in to the (Nov) 23rd date and I want to finish it off by renting out Staples (Center) myself and giving a free concert to anyone in the world that wants to come to the 'California Dreams' Tour as my last show."
