Ryan Sweeting is still on cloud nine. Kaley Cuoco's new husband opened up about being a newlywed while attending the Delta Air Lines Grammy party with the Big Bang Theory actress on Thursday, Jan. 23.

"It's amazing. You love it. It's honestly -- it hasn't been much different for us," he told Us Weekly of married life at L.A.'s Soho House. "Just our whole outlook on life I guess is a lot more positive. We couldn't be happier. It's the best moment of our lives."

Cuoco, 27, and the 26-year-old tennis pro tied the knot in a romantic New Year's Eve wedding in Southern California. Us exclusively confirmed their engagement last September after three months of dating.

"The second I got here I didn't want to go home," Sweeting recalled of meeting his love for the first time. "We spent every minute together, and I still haven't left from our blind date. So it's still going."

"Now I'm thinking as a husband rather than just as a boyfriend," he said of the slight transition from boyfriend to happily ever after. "It's making life a lot easier. I know what to do, and I definitely just do whatever makes her happy. That's pretty much it."

The couple enjoyed the event, which was also attended by stars such as Anna Kendrick, Ashley Benson, Lance Bass, Cuba Gooding Jr., Jena Malone and newly single Hilary Duff. Grammy-nominated singer Lorde was on hand to perform. "[They couldn't] keep their hands off each other," an insider told Us.
