Loved up koalas that stole Andy Roddick's 'thunder' were females!

Melbourne, Jan 8 (ANI): The two koalas that stole the limelight from tennis ace Andy Roddick with their lovemaking session, are both females, it has emerged.nd now, the same-sex marsupial couple, which was filmed bonding in the background of a Roddick interview in Queensland, has become famous worldwide.

The footage went global after the scene was posted on the couriermail.com.au site, and the amused American tennis star put a link to the website on his twitter account.

Brisbane's Lone Pine Sanctuary senior wildlife officer Karen Nilsson said the female koalas, which are normally kept separate from the males, express a readiness to mate by engaging in sex sessions with other females.

"When they are ready to be with a male, one of the things they do to express that is to pretend to mate another female," the Herald Sun quoted her as saying.

"As what happened with Sprite and Saffron, they often start in one position and then swap so they both get a turn," she added.

Nilsson said Roddick should consider himself lucky that the koalas weren't as vocal as they normally were, and that only two of the koalas were involved.

"He is pretty lucky actually because normally they are pretty noisy, so that definitely would have drawn some attention - they can be pretty vocal," she said.

"If they are all in season we have seen three or four of them together just going for it.

"People think koalas don't do anything but there are heaps of things going on behind the scenes that nobody knows about," she added. (ANI)
