What a view!

Heidi Klum found herself some time to relax on Monday and decided to share it with her Twitter followers. The 39-year-old Project Runway host tweeted a sexy snapshot of herself stretched out on a ledge overlooking the ocean, wearing a tiny black bikini.

"Finally . . . relaxation!" she wrote with the photo. Klum poses with her back arched and hands behind her head to show off her amazing beach bod.

The supermodel split from Seal in January after seven years of marriage. She is the mother of four children — daughter Leni, 8, sons Henry, 6, Johan, 5, and daughter Lou, 2.

After giving birth to her youngest daughter in 2009, Klum told Us Weekly losing the baby weight was a challenge. "Everything changes when you get older. It was different when I was 31 with the first one. Now, being 36 with the fourth one [daughter Lou], it's different." she explained to Us. "For me, it always works to get back into it immediately. I think that if you wait too long, it kind of sticks on and it stays there forever. I have to be motivated."

Last week, Klum tweeted, "Make time to workout even you're traveling" and attached some helpful tips on how to do it.
