Another insider shared that now Brittany is in all the photos, all the private suites, getting all the attention, “Blake is adjusting”.

“It’s not toxic — it’s human,” remarked a Hollywood insider.

The source went on, “Blake has always been the one by Taylor’s side at big events. Suddenly, someone else is sitting in that literal and metaphorical seat.”
