Need urgent Help about DS 160 Question

Am a student studying in foreign country but i wanna travel to USA but i came across this question:

Are there other persons traveling with you?

BUT I have a friend who is traveling to USA. my friend is married just got 2 years visa for 1st time. He wants me to go with him now he got his visa BUT he didn’t included he was going with a friend when he applied.

Can I include him in my application? Is there not any problem about that?

No, you need not mention that if he has not. Doesn’t matter.
