The 21-year-old beauty says she has been the victim of online intimidation since she began dating 17-year-old Reece.
"People send me messages on Twitter saying, 'I hate you, I can't believe you are dating my husband', but you just have to laugh at it," Rhiannon revealed.
"He's worth it, the death threats I can overlook."
Rhiannon, who plays April Scott in Home and Away, and Reece’s relationship seems to be heating up after their on-screen romance spilled over into real life.
They first met in June when she filmed a role on his video for ‘Shout It Out.’ Now, she happily reveals that they will be spending a weekend with Reece’s family in Adelaide, and she has plans to introduce him to her family.
"My mum is obsessed with him; she is very excited. I haven't seen him play live yet but hopefully I'll be able to take my family,” Rhiannon said.
“I feel privileged to be able to watch him. I think he's going to go so far."
The couple have regularly taken to Twitter to discuss their relationship. After photos emerged in OK! Magazine of the couple kissing in the street before heading back to Reece’s apartment, he happily re-tweeted fans’ congratulations to the couple and confirmed their relationship.
Still, Fish insists they were friends before love blossomed. "We became friends during the shoot and hung out on a ‘friends’ basis for a very long time," she said.
She was then in a two-year relationship with her Home and Away co-star Lincoln Lewis. When the pair split shortly after she returned from the shoot, speculation circulated that teenage singer was the cause. Reece has also denied the allegation, saying he was even friendly with her Home and Away co-star.
"I love Lincoln, I actually met him at the ARIAs," Reece told the Daily Telegraph.
"I don't think I had anything to do with [the break-up], I hope I didn't have anything to do with that.”
