Kendra Wilkinson is a proud user of the L-word!

The former Girls Next Door star, 23, gushed about the romantic vacation -- in Cabo San Lucas, Mexico -- in which her fiance, Hank Baskett, told Wilkinson those three little words on her blog Wednesday.

See sexy photos of Kendra from an Us Weekly photo shoot.

"We had soooooo much fun, and it was also the first time we said 'I love you,' which definitely made it one of the best vacations of my life!!!" Wilkinson wrote.

She included photos from their trip, in which she and Baskett, 26, rode four-wheelers.

"He told me he loved me two days before I told him," she wrote. "We were sitting out on the [hotel resort] balcony, and out of nowhere he just looked at me and told me he loved me!!! I was just like, 'OH MY GOD,' and I didnt know what to say. I was speechless!!!! Poor guy."

It wasn't until two days later, when the couple -- who will be getting married next month -- went parasailing that Wilkinson got the courage to say those words back.

"The two of us were up in the air, and ! was sooo scared, and I just told him to look at me, and at that very moment I told him I loved him!!!!" she wrote. "And the rest is history!"
