ANTHONY JOSHUA is packing on weight all over - apart from his head.
The heavyweight king showed off his new shaven look in a stunning topless photo for fans.
Watford's WBA, WBO and IBF champ posed menacingly with his hands together as he showed he is not slacking one bit in preparation for his fight against Kubrat Pulev.
European cruiserweight champ Lawrence Okolie was one of those to comment on AJ's pic, writing: "Prison scrap pending. Champ camp."
Joshua - who recently bumped into Tyson Fury in Marbella - also posted videos of himself in the gym.
The 6ft 6ins giant was on a watt bike and listening to Jay-Z and Rick Ross' track Free Mason.
Joshua sung along to the lyric: "I won't fail but a lot of men will."
AJ won his first world title in 2015 at 17st 6lbs, thrilled the planet with the 2017 Wladimir Klitschko win up at 17st 12lbs and out-muscled Carlos Takam at a giant 18st 2lbs six months later.
But the disastrous June 2019 loss to Andy Ruiz Jr - when Josh was a ripped 17st 9lbs Adonis - sparked a shake-up of his style, corner and size.
Joshua dropped almost a stone to outbox the bulbous Mexican over 12 one-sided rounds in December at a new slimline 16st 13lbs - his lightest in five years - looking unrecognisable in some pre-fight pics.
But the latest snaps from his Spanish vacation show a return to the mammoth KO artist that scored most of his finest stoppage wins teetering close to 18st.
A recent knee injury, that required a brace, will have limited the amount of fitness and cardio work Joshua - who melted hearts by chatting to an 87-year-old woman about boxing - could have done over the summer.
But it definitely looks like the dedicated ace has done a lot more then just pack on a few accidental holiday pounds.

And a couple of AJ's biggest fans have backed his return to the bulk.
Former cruiser and heavyweight king David Haye moved up from the 14st 4lbs division to beat 22st monster Nikolai Valuev.
And he supports AJ's plan to dine out on his power when he finally gets to face Pulev.
The Hayemaker also feels Fury's incredible demolition of Deontay Wilder has given fight fans an appetite for destruction that AJ cannot afford to starve.
Haye told SunSport: “I don’t think AJ needs to box against Pulev like he did in the Ruiz Jr rematch, he can box how he usually boxes, dynamic and explosive.
“He can go out there and use his physicality, his punch power, his angles.

“The world wants to see the world heavyweight champion do what Fury did to Wilder.
