Is it okay to have a gay crush?

You may be completely straight, in a long term relationship with your (wo)man, but still have a 'girl crush'/ 'man crush' on a celebrity.  I mean really? I personally have NO problems saying that Angelina Jolie is absolutely gorgeous as well as Victoria's Secret Angel Alessandra Ambrosio.  They have everything going on for them and I will admit that Alessandra Ambrosio may be my 'girl crush.' That is not saying that I have any hidden volitions or any homosexual thoughts about my 'girl crush' but it is just me acknowledging her gorgeousness. So I ask you...who is your 'girl crush' or 'man crush?'
