ETV quiz - question 1

The first of a very occasional series.  Using your encyclopaedic knowledge of the liveshows, answer the following question:

How old is Carolina?

Note: The answer is not quite as simple as it may seem.  Prize to the winner (a day out with Georg selling used cars).  Answer here as an edit on Saturday morning.

The answer is now so far down the page, lost in the speculation about Kaleya, that here it is again:

Hans says she's 18, Carolina says she's 21.  I think Hans may be nearer.

Kaleya has been refreshed by wellness like an old used mobile phone . Now she's younger and prettier than ever before.;-)))

Look at Kaleya's clip at ETV site for offline chat, "My number is 20, because I'm 20 years old". :)))))

In the April 2005 schedule Kaleya is 23 ... [hidden link - please register]

Since ETV started broadcasting in late 2004 Kaleya said she's 20, I don't buy her until I've seen her card. :)))))))

She said she was 21 one day when I saw her, she's turning out to be very nice too much better than those awful sunday morning shows from a while back.
But many of the models don't seem to be able to lie consistently as I have also heard Leti say she is 22, 24 and 26, so perhaps Carolina isn't 21 either :( 

26 years... but I want a day out with Carolina (she's my favorite!)!! :))

Very young, probably 20 years old but if you say that the answer is not quite simple as it may seem surely i'm wrong.
