Supermodel Linda Evangelista has split from her billionaire boyfriend, Hard Rock Cafe co-founder Peter Morton, according to a report.

The runway beauty, 48, began dating the business tycoon in 2006, when she was pregnant with her son, Augustin James, following a brief fling with French fashion mogul Francois-Henri Pinault - the now-husband of actress Salma Hayek.

Evangelista and Morton broke up in 2010, before reconciling months later, and he stood by her last year (12) as the stunner took Pinault to court in an explosive battle over child support.

However, it appears the reignited romance has since fizzled out, reports the New York Post's gossip column Page Six. The couple was last photographed together at a New York charity gala in March (13).

A representative for Evangelista has declined to comment on the split claims.
