Her Instagram handle may be "mizzhogan," but Brooke Hogan is on her way to being a Mrs., as the reality star got engaged over the weekend to NFL player Phil Costa.

"Happiest moment of my LIFE," Hogan, 25, wrote on her Instagram page, next to a photo of Costa on one knee during a trip to Las Vegas. "I am marrying my best friend. I wouldn't choose anyone else. I am so lucky and so grateful."

Hogan is the daughter of wrestler Hulk Hogan and rose to fame with her family's reality show, "Hogan Knows Best." In 2008, Hogan spoke out about her family's ups and downs, and how she felt about living life in front of the world.

"We definitely are honest with the audience about what's going on," she told "Good Morning America." "It is hard at times but you know, I saw the camera crew and I was like, 'I have to let you back in. You're so cute.'"

Things have seemingly become less dramatic with the family, as other photos on Instagram show everyone happily celebrating Hogan's engagement. But the cameras captured poignant moments too.

In another shot, Costa, who plays center for the Dallas Cowboys, is seen slipping a ring on Hogan's finger.

"I look scary," she wrote next to the picture, "but this is the face of total SHOCK."

And, pure joy too.
