Jennifer Aniston says calling Justin Theroux her husband feels ''natural''.

The 46-year-old actress made her first red carpet appearance since secretly marrying the 'Leftovers' star at the Los Angeles premiere of her new movie 'She's Funny That Way' last night (19.08.15) and was delighted with her newlywed status.

Asked how it felt to call Justin her husband, she told E! News: ''It feels quite natural. He's shooting 'The Leftovers' in Austin [now].''

The couple kept their nuptials under wraps by telling friends they were being invited to their Bel Air home for an early birthday celebration for the groom, and Jennifer says their determination meant they could pull off the surprise.

She said: ''Where there's a great will, there's a way. It can be done.''

After tying the knot, the couple jetted off on honeymoon to Bora Bora with friends, and the 'Cake' star told 'Access Hollywood' the vacation had been ''beautiful''.

Jennifer showed off her gold and diamond wedding band as she walked the red carpet and delightedly accepted congratulations from well-wishers.

An onlooker told People: ''People were congratulating Jen and she was really sweet and sincere when she thanked them. She seemed almost giddy!''
