Status is over 140 characters

When I try posting the following twit:

Ann Taylor Lace Dress on sale and Louboutin accessories on #Stylinity

I get System.Exception: Status is over 140 characters.
If I post the same text from Twitter, it shows 23 chars remaining and twits without any problem. The problem seems to be in having 2 URLs. Could you advise anything to solve the problem?
