Kristin Cavallari Showcases 'M' Necklace Amid New Romance with Mark Estes

The reality star's latest Instagram posts have sparked discussions about her relationship with the 24-year-old former football player.

Kristin Cavallari, known for her roles in 'Laguna Beach' and 'The Hills,' has been seen wearing a gold 'M' necklace, hinting at her new relationship with Mark Estes.
The couple made their relationship public in February, sharing moments from their vacation in Los Cabos, Mexico, on social media.
Estes, a former football player for Montana State University and Montana Tech, has been described by sources as 'really nice' and 'not your typical 24-year-old.'
Cavallari has faced criticism for the 13-year age gap between her and Estes but has responded with humor on social media.
Before Estes, Cavallari was married to former NFL player Jay Cutler, with whom she shares three children.
