Jennifer Lopez is down but not completely out. The R&B singer, who has been training for the Nautica Malibu Triathlon, has been resting for the last two days after injuring her ankle. But thatâs not stopping her from running. “She had a slight injury,” Lopez’s rep tells E!, adding, “She will definitely be doing the triathlon. She does not want to let down her charity and all the people who have supported her.” What she is out of is being the judge on an upcoming episode of Heidi Klum’s hit U.S. TV show Project runway Klum announced Lopez has dropped out of the line-up of the series’ finale on Friday, when Lopez’s appearance was scheduled to be recorded. Judge Nina Garcia hinted at the actress’ participation earlier this week, although producers failed to confirm the star’s stint on the show. Fashion guru Tim Gunn, who mentors the contestants, will fill in for Lopez.
