The young couple - who rekindled their romance just two weeks ago - were spotted canoodling on a secluded Bahamas beach after flying out for a VIP party at Paradise Island's exclusive Atlantis resort. The enamoured lovers frolicked in the surf and openly kissed in full view of holidaymakers.
Lindsay, 20, met the 26-year-old womanising model - the son of football legend George Best - in London last November, when she was hosting the World Music Awards. The pair have since enjoyed an on-off romance and last week Lindsay invited Calum to the premiere of her latest movie 'Georgia Rule'. The couple were spotted partying together in New York with the actress' mother Dina.
Despite their public display of affection in the Bahamas, Calum's spokesman does not think it will be a lasting relationship. Dave Read said: "Calum and Lindsay get on really well together. But this is Calum. We'll have to see." Lindsay and Calum both boast impressive lists of ex-lovers.
Calum has been linked to Kimberley Stewart, Elizabeth Jagger and Girls Aloud singer Sarah Harding, while Lindsay is rumoured to have enjoyed flings with James Blunt, Robbie Williams and Jamie Burke.
