Orlando never looked at wife Miranda the same way after Bieber flirt-fest in 2012

As the war between Orlando Bloom and Justin Bieber intensified this week, new info has come to hand about the basis of the beef… and it involves both Miranda Kerr AND Selena Gomez!

According to Page Six, the 37-year-old actor has been holding a grudge against his former wife ever since she was spotted flirting with the teen pop sensation at a Victoria's Secret show back in 2012, when Miranda and Orlando were still married!

"He never looked at her the same," a source close to Orlando spilled, which got us thinking… did something more sinister go down?

The Pirates of the Caribbean star made headlines when he attempted to throw a punch at the Biebs at a club in Ibiza earlier this week. Onlookers said that Orlando's blow-up was all down to a provocative taunt from Justin. "She was good," the 20-year-old was heard saying, in reference to Miranda. Ouch!

And it gets worse! After the minor throwdown, witnesses say Justin cockily told Orlando to "say hi to her" as he walked away.

Over at camp Selena, the 22-year-old is adamant that she had nothing to do with it.

Despite being spotted together on a few occasions, sources directly connected to Spring Breakers actress told TMZ that her and Orlando just happen to be in the same place at the same time often because they share a manager.

Another source previously said that Orlando had been a major support to Selena when she first broke-up with Justin, apparently he even invited her to do Buddhist chanting with him.

"He says chanting helps people turn poison into medicine and it doesn’t matter what religion you practice, anyone can benefit from chanting," the insider told HollywoodLife.com.

Erm, ok.
