Ellen Degeneres called paramedics after experiencing chest pains yesterday (26.09.11).

The 53-year-old talk show host was suffering from discomfort all evening on Sunday (25.09.11), and when the pain continued into the next day she called the ambulance service.

Within minutes paramedics arrived at the Warner Bros. studios in Los Angeles where she records her series and also a crew from the Burbank Fire Department.

Speaking in a segment which will be aired on the 'Ellen DeGeneres Show' today (27.09.11), she said: "What happened was last night I was having chest pains. So this morning the paramedics came to look at me. First of all, I'm fine ... I woke up in the middle of the night. I was feeling like a tightness of my chest and all the scary things ... like something was heavy on my chest and it was a cat so I moved it. I still felt the tightness and heaviness so there was another cat under that cat. There were two cats on my chest.

"Then I got to work and it was still happening. I was still feeling the pains. So I was like, 'You know, I should check this out. It's better to be safe than sorry. Who doesn't want to see a fireman occasionally? ... We called the paramedics here on the Warner Bros. lot and about 50 trucks and ambulances, like one Marching Band short of a parade showed up outside of my office. Then they come in with an axe. Break the door down. It was open. I don't know why they did that. They came in, they asked me all the questions, 'How are you feeling? When did it start? Family history? ... All the questions that they would ask but everything is fine."

Ellen - who is married to Portia De Rossi - has also thanked the paramedics for being so attentive and joked she has a particularly strong heart.

She said: "I have a baboon heart that I had put in earlier ... It's not true. But I want to say thank you to all the paramedics and the nurses who showed up and everybody for caring so much ... I appreciate it."
