"I feel very happy, very lucky and very much in love," Lukas said on the Today show March 27. "He's a good-looking man. There's something about being in London. I think I got a taste of the Brits and couldn't help myself."
In fact, his relationship with Chris came at a rowdy time for Lukas, who recently styled his curls into a sleeker look.
"I think this mane needed to be tamed," he joked. "I also needed to be tamed."
The pair first sparked romance rumors earlier this year after flirty social media exchanges and red carpet appearances together, including at Vanity Fair and TikTok's event Vanities: A Night for Young Hollywood event on March 8. The pair have since enjoyed skiing trips and a vacation to Mexico.
"We have fun together," Lukas added. "We go on adventures. He's the best."
Chris shared similar feelings of his partner in a March 17 episode of The Drew Barrymore Show, where he gushed about being "very happy" and "very much in love."
"I feel very grateful to be able to share my time with someone very special," Chris told host Drew Barrymore. "Love is a really special thing, and I think meeting someone you connect with is really, really special so."
