Leonardo DiCaprio has bought Blake Lively's dad Ernie a colouring book for his 64th birthday.
The 'Inception' actor presented the 24-year-old actress' father Ernie, who was celebrating his 64th birthday, with the item during dinner at Madeo restaurant in Los Angeles, and the actor was thrilled with his artistic gift
A source said: "Blake's father loved it."
Another source added: "[They] are so smitten it's crazy. I bet they get engaged in the next six months!"
The pair - who have been spotted on a number of luxurious dates around Europe - were recently seen spending time at Disneyland in Anaheim, California, with a group of friends after the 'Green Lantern' star attended the Mtv Movie Awards.
Leonardo - who missed celebrating Blake's 24th birthday yesterday (25.08.11) due to his 'Great Gatsby' filming Commitments in Australia - treated her to a helicopter ride to Saint-Paul de Vence, France, where they enjoyed a $500 lunch earlier this year.
