So huge that it would really hurt if you were Nick's BFF and didn't cop an invite to the celebrations.
Nick and Demi Lovato have been best friends since they were young, but the pair have faced some hard times recently, when Nick started dating Priyanka and then when Demi suffered from her overdose.
“Demi was so upset that she wasn’t invited to Nick’s wedding after everything that they have been through together. She has been his best friend forever,” a source told RadarOnline.
It's apparently why Demi unfollowed Nick on Instagram just last week.
According to the same source, Nick had his reasons not to invite Demi.
“Nick did not want Demi’s fame-wagon to overshadow him and Priyanka’s special day. Plus, he wasn’t certain that she was still going to be out of rehab at the time of his wedding.”
Unfortunately, it just seems like these two aren't friends anymore. Le sigh.
