Witnesses do not believe the woman was a relative.
The scenes come just days after Bachelor in Paradise star Keira Maguire confirmed that she and Jarrod Woodgate had split.
The news was confirmed during an Instagram Q&A session when a fan asked whether the pair were still an item. Keira responded with, 'No we are not.'
The pair unfollowed each other on Instagram in June, sparking whispers they had split.
The couple, who fell in love after meeting in Fiji on Bachelor in Paradise in 2017, have had a rocky ride since the start.
Moving in together after filming ended, they split in August 2018 only to reunite in January this year.
Keira opened up to New Idea during their last breakup where the reality TV star admitted she still loved Jarrod, and she saw him in her future.
It remains to be seen how she will react to these steamy Bali photos - but insiders suggest she 'won't be pleased at all'.
