Yes it can, if you add the required routes and rules.

But in my  mind if we use different MPLS from different vendor, example spoke1 using MPLS from vendor1 and spoke2 using MPLS from vendor2 then the traffic from spoke1 to spoke2 and vice versa will always passing thru the hub.

Even shortcut tunnel created since there is no direct connectivy between spoke1 and spoke2 there is no advantages using advpn.

Am i right?

Yes, they can speak....however the traffic will be proxied through the hub and not direct.  As MPLS cannot speak directly to DIA.
