Heidi Klum is making her more than one million Twitter followers salivate after posting a topless photo of herself relaxing on an island paradise while flashing some sideboob.

The model, actress and “Project Runway” host tweeted the words “Island speed ...” along with a photo of herself topless and showing ample sideboob. Klum was wearing a black bikini and lying on a towel as she caught some rays on the beach.

Klum’s photo has been popular on Twitter, with 193 users retweeting the picture and 373 users favoriting the topless shot. The model has more than 1.2 million Twitter followers.

“Will and Grace” actress Debra Messing was among those users admiring the topless Klum photo.

“So jealous!!” Messing replied, although she was apparently referring to the island paradise and not Klum’s sideboob.

Klum, 39, never revealed what beach she was laying on, but Us Weekly noted that the model was vacationing in Dubai recently.

Klum made headlines earlier this year when the “Project Runway” judge and host divorced her longtime husband, singer Seal.

The split came as a shock to the British singer, who famously still wore his wedding ring after being served with divorce papers.

Seal has since moved on, however, as the singer is reportedly eyeing a $6 million bachelor pad in Los Angeles, TMZ reported.

The Brentwood, Calif., home features four bedrooms and 5 ½ baths. Features include a fireplace in the master bedroom, two kitchens, a gym and a media room, according to the gossip website.

Klum told Us Weekly that she plans on spending the holidays with her children: Leni, 8; Henry, 7; Johan, 6; and Lou, 3.

"We're going to get a big Christmas tree and we might go to Disneyland. We go all over the place," Klum said back in October. "My children are everything for me. I've always wanted to have a big family. And I'm fortunate enough to have four."
