Not getting an invite to social events

Hi there, So i have been invited to a party on Saturday. BUT.. 2 of my best friends have been invited to another guy's pre-drinks gathering before the main party. I don't know him well but i would like to go otherwise i would be going to the party alone. I haven't been invited to the pre-drinks? I don't want to sound rude and invite myself, should i get my friend to ask him or shall i just leave it? Thanks
