My recent exs bestfriend is hitting on me?

My ex of a year and I broke up about 4 months ago. His best friend of many years has been texting me since the breakup, flirting with me, asking me to be his date, etc. My ex and I have been in no contact but I can’t help but think it might be right to let him know his ‘best friend’ is doing this. Or should I just leave it be and not tell my ex?
