In the video, the Bulgarian tennis player makes fun of his girlfriend of two years by saying that she is super critical of the tree that he picked out. Looks like they still have a pretty good relationship even after 20 months of dating!

This is definitely one way to intensify engagement rumors.

When asked by Fox Sports what she thought of all the rumors circulating her and Bulgarian tennis player, she said, “It’s a part of my life I like to keep to myself. It’s important to keep a part of you private and personal because so much of a professional athlete’s life is in the public eye.

“I have a him as a person and it’s nice to share each other’s company every day and forget about what we do, have other interests.

“If you are happy and that person brings you happiness, you have to cherish it as much as you can.’’
