The German supermodel began dating her bodyguard Martin Kristen last year, after she divorced her husband Seal. The two are blissfully happy and it's been suggested Heidi is already making plans to settle down with Martin!
An insider told National Enquirer: "She believes he's the guy who is going to make her happy for the rest of her life."
"She says he treats her better than any man she's ever had in her life and they're planning their future together," the insider added.
Heidi and Seal haven't divulged the reasons for their split, although the musician's temper is understood to have contributed to the break-up.
"When Heidi was at her lowest, Martin told her she had a beautiful spirit and that she deserved to be respected and loved," the source explained. "Their friendship has blossomed into a wonderful love affair."
