Cannot remember the title

Hi!
I'm looking for a book i read long time ago and dont remember the titile . It was contemporary romance, heroine met hero at the party, her mother and 2-3? sisters were very famous (probably singers). heroine was disabled - had problem with her foot, but it was not easy noticeable, because she was wearing prothesis? hero had a company with his brother, i think hero was architect or sth like this.. heroine's mother hired him for sth, thats why he was at the party... Thx for help :)
