Function to get url for UsersWP avatar

Do we have a function to fetch the URL for the current user’s avatar?

With Buddypress, I used to get the URL for the current user’s avatar like this:

$chat_picture_url = bp_core_fetch_avatar(array('item_id'=>$user_obj->ID, 'html'=>false));

I tried using get_avatar_url() but that gives me the gravatar (I don’t want that) instead of the UsersWP avatar.

I realize that there is shortcode available to display the UsersWP avatar, but I need to get the actual URL so I can supply it to another plugin I use.

I apologize if I overlooked this subject in the support forum; I think I searched thoroughly.
