Whose Birthday?

Just using this cartoon I did, can you tell whose birthday it is?

PS: Its not mine.
PPS: Its a regular visitor to this blog and they are on my sidebar.
PPPS: Alison got it right it is in fact Mother of six! yes six, Stine.
Click the cartoon to go and say Happy Birthday, she is 63 today.

Update: Okay she is not 63, she is 44 and her children are very happy I need to work on my cartooning skills some more :)
