Nothing official yet, but it looks like Hilary could be heading overseas to promote Elixir sometime in 2011. Rumors are circulating that Europe and Australia could be possible destinations for Hilary.
Again, this is not official, but it would make perfect sense for Hilary to promote Elixir in other countries. Hilary is very popular outside of the USA, and has many fans in Europe and Australia so she probably wants to expose Elixir to as many of those fans as possible.
If Hilary does go jet-setting to promote Elixir we can look forward to a bunch of new TV and radio interviews, which should be fun.
