Tennis champion Mark Philippoussis is gearing up to race at the celebrity event at this year's Australian F1 Grand Prix, which kicks off on Thursday, March 13. Philippoussis, whose career also includes a reality TV run as the eager-for-love bachelor on NBC's Age of Love, will be racing despite a knee injury that has forced him to walk with crutches for the past weeks.

Apart from this week's F1 event, Philippoussis is also looking forward to getting back in the court to secure a more glorious and fitting end to his sports career.

Age of Love bachelor Mark Philippoussis will be participating in this year's Celebrity Challenge at the Formula 1 ING Australian Grand Prix in Melbourne.   The 31-year-old Australian tennis champion will be joined by other celebrated athletes from a broad range of sports, including ALF, rugby, netball, athletics, soccer, surfing, cricket and basketball.

"Having a passion for cars and motor sport, I am really looking forward to the opportunity to be part of all the GP action," Philippoussis said.  "As a Melbourne boy, it will be great to see the city come alive for this event."

Every cloud has a silver lining, and for Age of Love runner-up Jennifer Braff, the silver lining turned out to be getting the opportunity to achieve her ultimate goal of reaching out to women everywhere.

The 48-year-old model and executive assistant, who came close to winning tennis star Mark Philippoussis' heart on the NBC reality dating series Age of Love, is planning to use her newfound fame to help women both physically and emotionally.

Braff told Reality TV Magazine last month that she would like to host her very own makeover show for the “new 40's plus woman.”

Jennifer Braff has not let losing NBC's Age of Love get in the way of accomplishing her goals.  The 48-year-old model, who was recently featured on the TV Guide Channel's latest special, Sexy Stars of Reality TV, has penned two books, both of which help older women like herself regain and maintain their youthful sexiness.

“I know there are many women out there that want [sexiness, excitement, and youthfulness back in their lives],” Braff told Reality TV Magazine.  “I received thousands of letters after doing Age of Love stating that I helped them in those ways.  One woman still writes me and since watching me on the show and getting back into the gym, has lost 18 pounds.  A couple wrote that I helped save their marriage.”

After learning about their “stronger than ever” romance from Confidential just nearly two months ago, many are speculating that Mark Philippoussis and Amanda Salinas, stars of the realty dating series Age of Love, are no longer together.  Controversy has sparked after Philippoussis' agent refused to comment on whether the couple is still an item.

Australian tennis player Philippoussis met Tennessee cheerleader Amanda Salinas on Bachelor-style dating show Age of Love, where he chose 25-year-old Salinas over 48-year-old Jennifer Braff.

After his controversial stint on Age of Love, Mark Philippoussis was more than eager to get back in the court to engage in some hardcore tennis action.  His efforts to get back in shape after his knee injury back in January proved to be successful as he made a victorious return to tennis when he beat former Australian Open champion Petr Korda at the Stanford Champion Series tournament in Dallas, Texas yesterday.

As reported previously, Philippoussis was supposed to take on Mats Wilander at the Stanford Championships.  But due to Wilander's lingering lower back injury, he was forced to withdraw from the event and was consequently replaced by Korda of the Czech Republic.
