'Smitten' with Australian author as steamy video shows lovebirds grinding at dive bar

EXCLUSIVE: Jillian Michaels goes wild! After split with fiancée the exercise guru parties with Ruby Rose, is 'friends with benefits' with her makeup artist and 'smitten' with Australian author as steamy video shows lovebirds grinding at dive bar.

Jillian Michaels has become Hollywood's biggest playgirl since splitting with her fiancée this summer and has been linked to a bevy of women, DailyMailTV can reveal.

The celebrity trainer called off her wedding to her long-term partner Heidi Rhoades in June after nearly nine years together.

Michaels wasted no time in moving on and has since been spotted all over Ruby Rose, L Word actress Tracy Ryerson and her makeup artist Chloe Francke.

The 44-year-old is said to be smitten with Australian author Tara Winkler, flying Down Under to spend time with the brunette and the two were seen dancing on each other at a bar in Sydney.

But insiders told DailyMailTV that Winkler, 32, is concerned that Michaels is not ready for a committed relationship just yet.

Michaels apparently became smitten with Winkler after reading her book and watching her Ted Talk on child protection.

She arranged to fly out to Sydney to meet the brunette and they quickly hit it off.

The two were still going strong in early August, when Winkler responded to a viewer's question on Instagram about dating long distance, saying that she gets 'lots of amazing text messages'.

But although Michaels is said to be head over heels for Winkler and stopped dating other women for her, the author is having second thoughts about dating a celebrity.

Adding to her concern the trainer wasn't ready to settle down, Michaels was pictured over the weekend snuggled up with actress Natalie Martinez.

On her Instagram story, Michaels posted a photo of Martinez resting her head on her shoulder and smiling as the fitness guru wrapped an arm around her.

Michaels has also been linked to Ruby Rose, starting when the two attended P!nk's Los Angeles concert together in early June.

Sources say the pair ended up going backstage and were 'all over each other'.

On June 8, days after they were seen together at the concert, Ruby commented 'Issa vibe' on a photo Michaels posted showing off her toned stomach.

Later in June, just a week after Michaels announced she had called off her wedding to Rhoades, she was spotted out in Venice, California, with L World actress Tracy Ryerson.

The two giggled as they walked down the street together.

And Michaels is also rumored to be in a 'friends with benefits' relationship with her close friend and makeup artist Chloe Francke.

The two recently went on vacation together to Miami, where they posted several pool side snaps, including one with their legs propped up on a lounge chair.

Michaels had been with her partner Rhoades since 2009.

The trainer made her very public wedding proposal during an episode of Just Jillian back in 2016.

The couple share two children. Lukensia, eight, was adopted from Haiti in May 2012. And Phoenix, six, whom Rhoades carried to term.

The Biggest Loser coach made the split announcement via Instagram.

'We’ve found we’re better friends and parents living apart than staying together,' Jillian wrote in a message to her fans.

'Life and people can change but our love for one another and commitment to raising our two kids as an inseparable team remains. Thanks for always loving and supporting us, the feeling is mutual.'
