The 36-year-old former ’Number One’ mistress of the famous golfer made sure everyone was watching as she put on a passionate display of affection with her new boyfriend Matt Hahn, who is close to 10 years her junior.

The couple put on a steamy show as they publicly embraced in the Miami Beach sea.

Bikini-clad Rachel showed off the curves which charmed Tiger in a skimpy patterned two-piece bikini.

And Matt was certainly enjoying the view, as he was unable to keep his eyes of the beauty as she stretched out to give him an eyeful.

At one stage the couple went for a romantic stroll. Walking hand-in-hand, they shared some smiles and giggles.

Matt also flaunted his own physique in a pair of patterned board shorts and showed off a chest tattoo, which appeared to be of a script design.

Rachel publicly professed her love for the insurance underwriter a few weeks ago.

She tweeted a picture of them saying: ’He’s the best thing that’s happened to me in as long as I can remember.’

Hahn posted his support on Twitter: ’Congrats, baby, proud of you’, when she graduated.

New York Post’s Page Six have reported that the couple plan to move in together in the Celebrity Rehab star’s $2million Park Avenue apartment in New York

All eyes on me, Rachel stretched out to give Matt an eyeful of her incredible bikini body

Rachel is understood to have previous experience of working ‘under cover’ and has now decided she is going to return to the gruelling profession on a long term basis.

The reality TV star traded in the glossy high life of celebrity parties and red carpet events to turn her hand to tracking down missing people.

New career, Rachel has recently trained to be a private investigator

The professional golfer’s ex-flame told the New York Post: ‘Obviously, people want to go down the ’cheating’ road, and assume it’s all about me finding cheating spouses. But I’m less interested in that.’

She added: ‘Missing people, cold cases, and I’m sure, a few liars out there who need to be exposed.’

The ex-Celebrity Rehab star is adamant this is no half-hearted career fling for her. She believes she can really help people and wants to be on the job, doing the real hard labour.

She insisted: ‘I want to solve cases for the underdog, for people who don’t have a voice.’

It is believed Rachel will be working for Detective Academy, DGA in Los Angeles, but will be based in their New York office.

Talking about the future, she revealed she hopes to one day set up her own private investigation firm.

She playfully added: ‘I’m thinking of calling it Puma PI…because I’m not yet a cougar.’

During the course of filming addiction reality show Celebrity Rehab, Uchitel spoke of how her father’s death and her tendency to impulsively enter into relationships contributed to her deep emotional issues.

This included her affair with the then-married Tiger Woods, which allegedly began in 2009 and continued into 2010.

Uchitel initially denied the allegations but admitted the story after more than a dozen other women came forward with their stories of infidelities with the world-famous golfer.

Woods and wife Elin Nordegren officially divorced in August.
