Max Key showing off new girlfriend?

Former Prime Minister John Key's son Max appears to have gone public with his new girlfriend.

The aspiring DJ and vlogger hasn't named the young lady, but is referring to her as "my fav" and "this one" on social media.

Max is the former boyfriend of beauty pageant runner-up Amelia Finlayson, with the pair documenting their relationship online with several cosy pics, before they confirmed they'd split in January, 2016.

While Amelia was a blonde, Max's mysterious new friend is a brunette.

"Summers been a real vibe with this one [sic]," he captioned a photo on Instagram with her earlier this month.

She has both hands on Max in the photo, which he also added love-heart and fire emojis to.

In a Snapchat he posted on Sunday, she has a hand on his half-naked body.

"With my fav," Max captioned the intimate image, together with more love-heart emojis.

Further confirmation on the pair's relationship status, along with the female's identity, should be revealed via social media soon.
