Should I tell my colleague that she smells?

I dont want to be rude to my friend/colleague but her odor does bother me a lot. What would you do if you were me?

She is new to my company and is assigned to sit next to my cubicle. We enjoy working together and share a lot about our life and work. Everytime, she needs help, i would come over and bend over to her computer to show her stuff and that momment is like torturing me due to her ordor. I have to hold my breath all the time when im standing next to her. There are about 15 cubicles in my office, so it is not so small, but i guess the AC being turned on really strong all the time does hold the smell. As soon as i enter the office and feel that smell, i know for sure that she is there and i never be wrong!! I notice that everytime she put her hair down (i guess she just wash it or take a shower right before coming to work,) the odor is much less. I never tell this to anyone but her body’s odor does bother me through a day. I cant focus on my work at all and it has been over a month since she started
