The 30-year-old from Sydney, who goes by the moniker "Matty J", said he's "oblivious" to his newfound fame, despite being on one of the most watched, and gossiped about, shows in the country.

"I got my old job back at a marketing agency and I work nine to five Monday to Friday, so my life is kind of boring still," he told Fairfax Media.

"I love marketing though and I think it's good to have a job like that, it just keeps you grounded and allows life to feel that little bit normal."

Dressed in a blue Calibre suit, Johnson was speaking from the black carpet of the David Jones Spring Summer 2017 fashion launch where he was under strict orders from Channel Ten not to speak about the reality show - to the ire of some, but the surprise of none.

It was his first outing at such a celebrity-filled event, and although he was plagued for selfies from starstruck socialites and models, he said he didn't feel like he fitted in.

"I don't think it's for me. I'm more the kind of guy who will be sitting at my desk writing emails and marketing proposals," he laughed.

"My friends don't really care that I'm The Bachelor to be honest, my work colleagues don't care either, but it's an occasion like this that will make you realise you are doing something different than your old life."

After being dumped last year on The Bachelorette finale by Georgia Love, fan-favourite Johnson landed his own series, starting out with 22 eligible bachelorettes, so far ousting eight.

One of those, Natalie Holmberg, this week described living in the bachelorette house as like being in a "big, oestrogen-filled zoo" ??? and revealed that casual nudity among the women was commonplace.

"We got around naked in that house. It was a bit of a nudist colony," she said.

You could ask Johnson if he had the same experience, but he's been gagged.
