Tom Hanks has shared a throwback of himself and his wife to celebrate their 30th wedding anniversary.

The 'Sully' star toasted 30 years of marriage with Rita Wilson on Monday (30.04.18) by taking to his Instagram account to upload a picture of them on their big day in 1988 alongside another snap of the pair more recently.

He added the caption: ''30 years on April 30. '88 To '18. Magic numbers. Hanx and @RitaWilson (sic)''

Rita also posted the same picture of the couple, and admitted she is ''grateful'' they have been together for so long.

She wrote: ''April 30,1988-April 30,2018 Thirty on Thirty. Keeping love alive. Grateful. (sic)''

Tom, 61, opened up about his love for his 61-year-old wife last year, admitting he knew there was something ''crazy great'' about his significant other on the day he met her.

He said: ''I will say that right from the get-go, I thought there was something crazy great about her.

''I met her and I thought 'Oh lord' ... there's something cookin' here.''

'My Big Fat Greek Wedding' actress Rita previously gushed over Tom - who she has sons Chet, 27, and Truman, 22, with - revealing he assured her during one of their first meetings than she would ''never have to change'' during their relationship.

Speaking in 2012, she said: ''I'll never forget, we were standing on the corner of 57th and 5th in New York, or 58th and 5th.

''We were holding hands and we were waiting for the traffic light to change. And he looked at me and he said, 'You know, I just want you to know, that you never have to change anything about who you are in order to be with me.' ''
