"We love him," Dina gushes to ET about her daughter's beau. "He is a sweetheart. My other children and I love him. We know him well."
"I have even FaceTimed with his mom," she adds, revealing that her daughter and Egor have been together about six months. "He is just so sweet, and they are so happy. Everyone is so happy."
Lindsay, 29, recently got candid about her latest relationship in a tell-all interview with The Sun.
"I do have a boyfriend, and he is a great guy," she told the British paper. "I met him in the summer. I'm really happy."
But the former child star was careful not to credit Egor with any of her accomplishments.
"If I have ever been linked to someone, they always say, 'This guy is so good for Lindsay, look at how he has changed her'," Lindsay said of her past romances. "I am just like, 'F*** you', because I have done this for me. I take care of myself and then they just set it up to fail."
Last week, Lindsay posted a photo of a shirtless of her new man to Instagram with the caption, "I love him."
