Stephen Bear was reportedly arrested at London's Heathrow Airport this morning.
The Celebrity Big Brother star, who turned 31 today, is said to have been taken into custody as he returned to the UK from Dubai after moving to the city last year.
A spokesperson for Essex police told The Mirror : "A man has been arrested in connection with an investigation into the disclosure of sexual photographs without consent.
"The 31-year-old man from Loughton was arrested on Friday 15 January on suspicion of disclosing private sexual photographs or films without consent with intent to cause distress, harassment, and obstructing a police officer.
"He remains in custody for questioning."
The Daily Record has contacted a representative for Stephen Bear for comment.
Stephen found fame after starring on the Channel 4 series Shipwrecked back in 2011, where two teams competed with each other for new members, with the larger team winning a cash prize at the end.
The star went on to appear in several reality TV shows, including MTV's Ex on the Beach and Celebrity Big Brother, when he was crowned the winner.
He then went on to present Just Tattoo of Us with former Geordie Shore star Charlotte Crosby, with the pair dating on and off from 2017.
