Milo Ventimiglia has tried to keep his personal life out of the spotlight. But he may have confirmed his relationship with Kelly Egarian when he took her to the Emmys last weekend. While they didn't walk the red carpet, they did sit next to each other at the ceremony. They snapped a selfie together at the Microsoft Theater and packed on the PDA.

WHEN WILL WE FIND OUT HOW JACK DIED ON 'THIS IS US'?

"When Milo and Kelly entered the theater, they paused at the top of the stairs so that Milo could take a selfie. He seemed to want to capture the moment for them," a witness told ET. "They then turned around to walk and find their seats with their arms around each other. Milo and Kelly were definitely not hiding that they were here together."

2. Mandy Moore

WHY FANS WERE DISAPPOINTED BY THE 'THIS IS US' FINALE ...

"He did a very good job," Moore told ET of her new bling. "Yeah, I'm not an engagement ring kind of girl. I'm a bashful girl and I didn't think I really wanted one, but then — I'm very happy with this. Because you can see my skin underneath. I like that."

CHRISSY METZ HAD AN EPIC RESPONSE TO WEIGHT CRITICS!

"[We are] just enjoying life together," she said last month. "You know, we work more than we don’t work so when we do get some time with each other, we enjoy it. We went to a Dodgers game [recently] … we’re just living life. I’m not rushing into anything, and I don’t think that when you really care about somebody that you need to."

4. Justin Hartley

Justin Hartley announced his engagement to Days of our Lives actress Chrishell Stause in 2016, and they plan to tie the knot later this year. Hartley previously said they wanted an "intimate" ceremony, but they are leaving most of the work to their wedding planner.

"We obviously have our guest list and stuff. We’re having fun. She’s having fun picking out her dress," he told Us Weekly. "We’re doing it in the right way. We hired a very competent wedding planner. She’s doing all the hard stuff, so basically we just field phone calls, and go taste cake and food. We’re having a blast doing it."

5. Sterling K. Brown

Two-time Emmy winner Sterling K. Brown has been married to Ryan Michelle Bathe for more than a decade. Bathe has even guest-starred on This Is Us as Yvette, the mother of young Randall's African-American friend.

When accepting his Best Actor Emmy last weekend, Brown's speech was cut off before he could thank Bathe on stage. But he gushed about her in the full text of the speech, which was later published in Variety and The Hollywood Reporter

"And to my wife — they cut me off before I got to thank my wife, man!" he wrote. "Ryan Michelle Bathe, you're everything. You make my life worth living and you gave me two of the most beautiful things that God has ever put on this planet: my sons, Andrew Jason Sterling Brown, Amaré Michael Ryan Christian Brown, your daddy loves you with the strength of 1,000 suns."
