Justin Bieber and Selena Gomez back together for holiday romance

selena-gomez-justin-bieber-rumor-has-it.jpgIf Justin Bieber and Selena Gomez don't want anyone to know they're probably dating again, they're not doing a very good job of hiding it.

Mutual friends Alfredo Flores, Jas Prince and Lil Twist all shared evidence via social media that the on-and-off couple is on again.

Bieber and Gomez can be spotted in the shadows at the tail end of Prince's July 4th Instagram video.

Bieber's pal Flores also posted a Fourth of July Instagram video featuring Gomez (without Bieber), but Prince's Tweets suggest Flores and Bieber were hanging out over the holiday.

And Twist Instagram-ed separate pics of Bieber and Gomez only hours apart.

But the real bombshell? This photo Bieber himself Instagram-ed with the hashtag "#heartbreaker":
