Sam Burgess and Lucy Graham’s X-rated appearance at the very posh Byron Bay Hotel – and his tightly laced ex Phoebe definitely wouldn’t approve

NRL star Sam Burgess’ new girlfriend, Lucy Graham, is proving to be the polar opposite of his ex-wife Phoebe.

While the former wife Burgess is known for her demure demeanor and elegantly curated Instagram feed, Lucy boldly showed her wild side on Monday as she posed with Sam for a racy Instagram photoshoot.

The couple stood on a flight of steps outside the posh Byron Bay Hotel Raes, with Lucy, 33, comically poking her pelvis into Sam’s rear end.

Lucy grinned triumphantly as she pulled her suitor’s bum towards her hips while Sam, 34, closed his eyes and pretended to flinch.

In a second photo, the pair could be seen bursting out laughing.

“He’s a real bad gal,” Lucy captioned the post, tagging her burly beau.

Lucy looked chic in a white singlet and beige trousers, while Sam wore a black t-shirt and matching shorts.

Sam’s family members were clearly amused by the bombastic post, with his sister-in-law Joanna commenting: “Yesssssss! cheeky cheeky.’

His brother Luke, meanwhile, poked fun at Sam and Lucy for wearing matching white Birkenstock sandals, writing: “Birkenstock ambassadors for sure!!!”
