Adams, who hit the gym ahead of her Bonds photoshoot as an undie model recently, said she's looking forward to the challenge too.
"I was hesitant at first because I have such a hectic schedule. The fitness regime is intense, but I like feeling fit and motivated.
"My friends on Shorty were, like, 'wow, you're so courageous to do it, that's so impressive.'
"I guess I didn't realise at first how physically demanding it was, but everyone is so supportive and this will be a great achievement for me," she said.
"Besides, my body is everywhere in the Bonds ads - on billboards, on the back of buses - so I'm not too worried about stripping down and getting in the ring," she laughs.
Clean and green ambassador
He saves lives on screen as an ambulance officer, now Shortland Street star Cameron Jones, 24, is using his fame to draw attention to meaningful causes - dropping Auckland's carbon levels and encouraging young people to vote tomorrow.
Shortland Street actor Cameron Jones, "the Kiwi Leonardo de Caprio".
The environmental activist, who's been called "the Kiwi Leonardo de Caprio", told The Diary he believes there's too much peer pressure and bullying on young people to be apathetic about politics.
"There's really a strong political tall poppy syndrome in New Zealand, where young people think it's uncool to get behind politics, and I think that's sad.
"If you hear or read comments young people make to each other in person and online there's a real feeling of bullying and putting people down if anyone shows an interest in politics. It's an insecurity complex. They think it's not cool.
"But I think it's cool to be politically involved. It doesn't matter which party you support.
"Young people in New Zealand have an attitude where it's cool to hang back and not have an opinion, or stand for something, because if you put yourself out there, you're open to criticism.
"They'll happily discuss rugby or the Kardashians, but they won't discuss issues of real importance."
Jones, who is also an ambassador for climate change movement Generation Zero and NZ Shark Alliance banning shark finning, took to Twitter yesterday to encourage young fans and followers to vote.
Electoral engagement isn't his only passion. He's on a sustainability think-tank and gave a speech before Auckland Council and business leaders recently about the move into a low/zero carbon city. He thinks New Zealand could be world leaders, like Denmark.
"Being low carbon is not about the Government or left vs right wing. It's not about the hippie stoner green movement, it's moved on from that," he said.
"It's about finding sustainable working solutions that makes smart money for the economy."
X-man on Cuba St
He was spied at Wellington's Laundry bar on Tuesday night, and walking down Cuba St, but Hollywood star Michael Fassbender is keeping it low key. There were no star trappings and trailing paparazzi.
The A-lister is in New Zealand to shoot the movie The Light Between Two Oceans at a remote Marlborough location, believed to be Stephen's Island in the Sounds.
Filming will follow later in Dunedin and around Central Otago.
There's been no sightings yet of Oscar winner co-star Rachel Weisz, who plays his wife in the movie, a DreamWorks Studios' adaptation of a book by M.L. Stedman.
Ali's wedding rumours
Rumours are swirling that RadioLive host Alison Mau has secretly tied the knot with her fiancee Karleen Edmonds - but she is staying mum.

Calls and messages to Mau this week were not returned, and a MediaWorks spokeswoman would not confirm or deny the nuptial news.
Co-host Willie Jackson played coy when The Diary phoned. "Um, I don't know what you're talking about ... what wedding?" However, wedding talk is being speculated at the company. "Ali is definitely wearing rings on her ring finger. She went away for a few days and, well, people are saying she's married."
Mau did tell The Diary this year she would keep her wedding day simple and no fuss because neither woman "was a Bridezilla".
"We just want to be married. We're not brides.
"It will be a small wedding, and any weekend will do," Mau said.
Edmonds and Mau became engaged in March 2012, after a two-year romance.
Henry's Mustang sally
The last time he left the show for a holiday his ratings dropped, so will Paul Henry fret when he leaves the swivel chair next week for a quick sojourn to America for the launch of the new Ford Mustang? He's buying a red one, incidentally.
Radio Live host Ali Mau, The Edge Breakfast presenter Mike Puru and gung-ho reporter Rebecca Wright will stand in for Henry as guest hosts of The Paul Henry Show next week.
Ali Mau will be in the hot seat on Wednesday, followed by Wright on Thursday night and Puru on Friday.
Last time the car enthusiast was awol, producers chose some fill-in hosts who hadn't been in front of the camera for several years, but Mature TV does not seem to be the go this time.
