The Victoria's Secret model - who tied the knot with the 31-year-old Kings of Leon frontman at San Ysidro Ranch in Montecito, California in May 2011 after two years of dating - is never happier than when her spouse treats her to a romantic dinner at home.
Lily, 27, told Us Weekly: ''Cooking dinner is very romantic and gets you lots of points. My husband cooks,. Whenever he cooks me dinner, I think it's very romantic.
''He does amazing steaks that are really delicious.''
Lily - who walked down the aisle in a custom-made Vera Wang gown - has said her wedding was perfect and she wouldn't have changed anything about the sunset ceremony.
She gushed: ''It was really an amazing day. It was more beautiful than I could've imagined.''
The couple welcomed their first child, daughter Dixie Pearl, in June and Lily has never been happier.
She previously said: ''Married life is the best. I'm so proud to be a wife.
''Caleb is the man of my dreams. And you can quote me on that.''
