I found this article in one of mum's gossip magazines so I'm not sure how much truth is in it

basically it says they're still together. Very confusing (and typos are mine not theirs

)
Hewitt Family Feud
Jaslyn Hewitt is a tennis pro living in the shadow of two great men-her brother Lleyton and her long-term beau Joachim Johansson
The Hewitt family Christmas will be even more joyful this year, with the arrival of Lleyton and wife Bec's new daughter Mia. But behind the baby talk there will be tension between Lleyton and his sister Jaslyn over her love match with tennis heart-throb Joachim Johansson, who will join the family in Australia for their festivities.
There is rivalry between Lleyton, 24 and Joachim 23 on and off the tennis court, and Jaslyn is caught in the middle. She's torn between her love for her brother and her undying love for her boyfriend, whom she calls Pim Pim. The tension stems from both mens' competitive streaks. Lleyton has been the world's number one men's tennis player and is now number four. Joachim not only dreams of climbing into the top 10 but wants to be number 1 in the Hewitt household.
"Joachim wants Jaslyn to admire him as much as she idolises her brother, and that means winning a grand slam and wiping the floor with Lleyton in a big match," US tennis writer Mark Moore says. "But he has a good deal of hard work in front of him before reaching his goal and impressing her."
The competition between Lleyton and Joachim came to a head last year, when they went head to head in the US Open semi-finals, the only time the pair has played a professional match against each other.
Jaslyn screamed her lungs out for Joachim, shouting her brother's trademark C'mon when he beat Andy Roddick in the quarter finals. But she was far more sedate when it became a family affair and Joachim faced Lleyton in the semi.
In fact the match-up divided the whole family, with Lleyton believeing that even though she's dated Joachim for five years, his sister would root for him.
"It has to be her brother," Lleyton said when a reporter asked who he thought Jaslyn would support. When Joachim was asked the same question, he replied: "She can't choose her brother but she can choose her boyfriend so she'll be shouting for me."
The pressure was on Jaslyn from her Swede-heart (

) to sit in his family box while her parents wanted her to join them in Lleyton's box.
"Discreetly, she ended up choosing a private neutral suite away from the prying eyes of the TV cameras so that her emotions, presumably in favour of her boyfriend, would not be seen," Mark says.
"But Lleyton may have been very upset Jaslyn wasn't supporting him. After all, she's not engaged yet."
Joachim eventually lost the contest in straight sets, 6-4, 7-5, 6-3.
After the match, Lleyton made comments to reporters that angered Joachim, telling them: "I haven't spent a lot of energy out there" and later adding "He;s got talent, but obviously he's a little raw at the moment."
Joachim has spent the last two Christmases with the Hewitts in their Adelaide home. This Christmas, the Hewitts and Joachim may be spending December 25 at Lleyton's Sydney home so he and Bec won't have to travel with a new baby.
Joachim, famed for his rocket serves and bullet forehands, has practised with Lleyton on the family's backyard court in Adelaide. They have since stopped hitting together because Lleyton is said to be afraid Joachim will learn how to beat him.
Living in the shadow of the two tennis stars has made Jaslyn realise she hasn't fulfilled her own potential. In 2000 the same year she met Joachim in Australia at a small tournament, she was Australia's number one junior but it's been downhill since.
After a reported recurring wrist injury, Jaslyn has slipped to number 599 in the professional rankings after achieving a career best of 304 in May.
She has only earned $11, 000 this year and was devastated in January when she was overlooked for a wildcard into the Australian Open and then lost in the qualifying to slip out altogether.
"Her ranking is now even lower and she's unlikely to get a wildcard spot for the 2006 Open" Mark says.
On the positive side, the flat spot has given her more time to spend with Joachim, who had to undergo surgery on his right shoulder in July and will not return to the circuit until after the Open.
Jaslyn joined Joachim at his home in Sodertalje, Sweden to care for him while he recovered from the operation. Then, when he moved to Monte Carlo to avoid brutal Scandinavian taxes she joined him there also.
Last year, Jaslyn and Joachim confessed their love for each other on the Seven Netwrok TV program Slam! Road to the Australian Open.
Jaslyn and her hunky 198cm tall Swede are
still very much head over heels and despite persistent rumours suggesting a break-up and that she has retired from tennis,
insiders speculate the happy pair are about to get engaged.
"In light of the fact she's been there for him day and night during his recovery it would be no surprise to anyone on the circuit that Joachim will pop the question in the near future, probably even while they're in Australia." says Mark.
