TikTok star Sopha Dopha - real name Sophia Begg - recently celebrated her 21st birthday in style with a wild party on the Sydney Harbour.
Throughout the day, Sophia could be seen making out with a mystery beau who she has been dating for about one year.
The online personality, who boasts 1.3million followers on TikTok, has yet to show his face, only sharing her partner's voice off-camera or in photos shared to her Instagram with his head cropped out or covered by her hand.
Sophia took to her socials in December with a slew of content from her birthday celebration and she unwittingly revealed the identity of her high school sweetheart.
Daily Mail Australia can reveal Sophia's man of mystery is Simon Collis, who she attended Terrigal High School with before enrolling in St. Joseph's Catholic College in East Gosford.
Simon, 21, has a private Instagram account with 443 followers and has made a mere 11 posts. His display picture shows the young couple posing together in his bedroom for a selfie.

Simon comes from a close knit family and is the youngest of three siblings, including an older brother and an older sister.
His father Andy Collis is an expressive painter and art academic, who attended Sophia's 21st birthday party alongside his older brother Tom and Tom's wife, Rachel.
'Great night on an amazing yacht cruising around Sydney harbour last night to celebrate the 21st birthday of a beautiful friend. Xx thank you S. X,' Andy captioned a carousel of videos and photos from the early hours of Sophia's debaucherous birthday celebration.
In it, Simon can be seen relaxing with his family members and later, dancing with them aboard the rented yacht and Sophia's scantily clad besties.
'Looked like a wonderful birthday party. I'm still waiting for 'S' to be revealed,' a family friend comment on the post, referring to Simon.
The young couple appear to be smitten, with Sophia also commenting on Simon's dad's posts.
He celebrated his own 21st birthday last April, with Andy sharing a touching tribute to his son on Instagram, writing: 'It’s our youngest child’s birthday: Simon is 21!! I love you, son - more than you’ll ever know. Have a brilliant birthday. X.'
It's unknown which profession Simon is in, however the entire Collis clan makes annual visits to volunteer at Kirsten Jade Children’s rescue center in Thailand - an orphanage housing 50 children in Chiang Mai.

Simon and Tom appear to be continuing this work, with Tom sharing a GoFundMe online.
It's entirely possible that Simon, who has little to no social media presence himself, is reluctant to be served up to Sophia's Gen Z following for dissection or comparison to her influencer ex-boyfriend.
His name has been surfaced and shared by her most obsessive followers for several months now already, with the TikToker giving no answer as to why she hasn't shared her boyfriend's identity online.
She shared a video to TikTok in June, in which she appeared to take aim at ex Jordan Menadue - of Fitzroy Garage Sesh internet fame - while lashing out at an unnamed ex.
In the now-deleted TikTok, the influencer wrote: 'I have my own business, dream car, investment property and it’s probably because I don’t have to pay for everything for you anymore.'
The video received mixed responses, with some fans slamming Sophia for flaunting the fact that she's a landlord and for taking a swipe at her ex whilst in a new relationship (with Simon).
'Honestly ridiculous how long these comments/videos have gone on for without me saying anything,' Jordan wrote back in his video, which gained more than 644K views.
'It is a form of online bullying and you need to be called out for it. Be a good role model for your millions of young followers. Please leave me alone. Thank you. #don'tbeabully.'
Sophia was quick to reply a mutual friend's comment, which read: 'People know how much of a good human you are Jordan'.
'Don't forget when we went to dinner when I first moved to Melbourne and you said don't date him everyone in Melbourne doesn't like him'.

As the messiness continued to unfold on social media, online gossip sleuths began to screenshot and share the tea in a popular “Tea Time” Facebook group.
Days later, the embattled internet model was forced to deny claims she was rude to DJ Maddy Spencer at the TikTok Awards.
Several months out from her 17th birthday, Sophia posted her first video to TikTok.
In an interview with Stellar magazine, the influencer said that a nine-month bout of glandular fever during Year 12 dashed her HSC results and lifelong dream of becoming a doctor.
