OMG I'm so embared this happened. What should I do?

Well, my boyfriend picked up for a date and he opened the door for me to get in on my side. Well I did and while he was making his way over to his side of the car to get in the driver's seat, I let one rip. I didn't want him to hear me farting. Well I didn't notice that there were two of our mutual friends sitting in the backseat. they heard me fart! Not to mention the whole car smelled. nobody said anything, but i know they were laughing about me behind my back.
