Christopher Lambert, famed for portraying Tarzan in Greystoke: The Legend of Tarzan, reportedly collapsed during a fan convention.

The 69-year-old Highlander icon, as reported by TMZ, faced the medical emergency at the convention that took place at Steel City Con in Pennsylvania on Saturday.

Lambert was said to be signing autographs for his fans when the mishap occurred after which he was transported to a medical center immediately via ambulance, an eyewitness told the outlet.

Following the medical emergency, a spokesperson for Lambert told the publisher that he was doing "perfectly okay" and was taking some break back in his room at a hotel.

The reason behind Lambert's collapse was revealed by his rep, noting that it was due to a sudden drop in blood sugar drop and lack of sleep plus improper diet.

The legendary actor, also known for starring in films such as Mortal Kombat, was also scheduled to make an appearance for another meetup at the same location, however it is not confirmed yet if Lambert will attend it after his medical scare.

Moreover, the convention also addressed the Lambert's collapse by posting a public statement on Facebook, reading, "Christopher Lambert had to leave the event due to a personal issue. Return time TBD. Photo op canceled.
