The Movie Show reporter (25) also admitted that since then she has a serious 'girl crush' on actress Nikki.
"I interviewed the Twilight cast when they were over in Dublin," Daniella told the Diary.
"I wasn't the biggest Twilight fan beforehand, but now I'm a total Twihard. I was told to watch one movie for research for The Movie Show and ended up watching all four in one go. I really got into them.
"I just spent the whole time thinking: how have I missed out on these films? I get what all the hype is about now and can kind of understand why their fans are so loyal."
But it wasn't Hollywood heartthrob Kellan Lutz who caught Daniella's eye.
Instead the Kildare native was enchanted by Nikki Reid, who plays Rosaline in the vampire franchise.
"She is my new girl crush," the model laughed.
She was even serenaded by the Thirteen actress.
"She is just so beautiful and so talented. She and her husband sang a song when I met them and she has an amazing voice and she's really, really nice and warm and chatty and hugely successful and gorgeous.
"So yeah -- she impressed me."
Daniella says she's uncertain if she has what it takes to become a serious actress like Nikki, but loves doing comedy sketches with The Republic of Telly lads.
"I'm really into my comedy. I'm a comedy nerd, I met Ross Noble recently and was thrilled. I don't think I would ever like to be a proper serious actress, but I really enjoy doing all the skits on the Republic of Telly."
This season, Daniella features in a mini-series with Eddie Durkin and the rest of the Hardy Bucks boys. "They've got their new movie coming out -- which I can't wait to see. I'm doing a mini-series with the guys and it is such a laugh. I really enjoy it."
Daniella says she likes seeing good female actresses and comedians on screen.
"I really like funny quirky girls like Katy Perry and Kristen Bell. I like seeing them act and I think it's great to have strong female comics. And I like to think I'm slightly amusing if slightly idiotic, so doing that kind of stuff on the Republic of Telly is a great outlet for me."
Daniella says working on the RTE's latest The Movie Show has been an incredible experience, but it's not all glitz and glam.
"We really get into the thick of it. It isn't all red carpet events and after-show parties -- not at all," she said. "We're on set and behind the scenes -- testing out special effects. Believe me, it's not glamorous, but it is fun."
