She was accused of cheating on former boyfriend Tyler Posey after rumours claimed her old romance was still going on when she was with Charlie.
However, she rubbished the claims saying her and Tyler were broken up and she was not with Charlie.
She also appeared as Hilary/"Larry" in Blended and as Celia in Alexander and the Terrible, Horrible, No Good, Very Bad Day.
In 2015, she played Madison in The Duff, Amanda in Perfect High and Hazel in Big Sky.
However, it doesn't look like the subtweets are affecting the new couple one bit.
Previously, some barbed tweets flew back and forth when Bella became involved with Tana.
And while it is, of course, Bella's prerogative to date whoever she likes, it appears that one of the involved parties isn't so happy about her latest dating development.
Bella and Mod Sun have been shouting each other out on social media and making public appearances together, but fans think that Bella's former flame Blackbear isn't thrilled about their new romance.
But don't jump to conclusions yet; they're not dating or back together.
(Let's just say they haven't gone full Jelena.)Apparently, the two "have been in contact" since the singer (née Abel Tesfaye) broke up with Selena Gomez after 10 months of dating.
