Blake Lively is seriously panicked over all the backlash she’s been getting on social media and throughout Hollywood – so she’s turned to best friend Taylor Swift for guidance and advice about how to ride out the storm that’s threatening to engulf her entire life, a source exclusively tells Life & Style.

“Even though Taylor’s busy with her tour in London, she’s been solid as a rock for Blake,” the source says.

“She’s calling and texting all the time to cheer her up and remind her not to let all the negativity get her down, that it’s par for the course when you make a big impact.”

Blake, 37, hasn’t posted to Instagram since August 8, one day before the premier of It Ends With Us.

As Life & Style previously reported, the Gossip Girl actress decided to take a social media hiatus after being labeled a “mean girl” by online fans amid backlash on her promo tour.

Many commenters blasted the star for making “tone deaf” remarks about domestic violence while promoting the movie, which deals heavily with the subject.
