whinging noise

[SS Shaun]

So i took the car out today and had some fun but i noticed a small issue. ones i got to about 35mph i hear a whinging sound. I thought it was coming from the rear end but after having my wife in the car she says it sounds like its coming from the front end. I only hear the noise on a deceleration. if i step on it the noise goes away as soon as i let go of the gas i hear it again. I know i need a wheel alignment but could that be the issue? any thoughts?
