Stolling round New York's Washington Square Park with Alec's daughter Ireland, the couple held hands and shared loving glances.
And their brand new wedding rings could clearly be seen shining away on their fingers.

Hilaria, who has taken Alec's surname, wore a silk magnolia trumpet gown with cap sleeves by New York-based bridal designer Amsale Aberra.
The groom, pictured arriving at the church, looked dapper in a suit by Tom Ford.
During the service their were readings in Spanish, paying tribute to the country where Hilaria spent much of her youth.
Famous faces present included Woody Allen and his wife Soon Yi and Alec's 30 Rock star Tina Fey.
family members included Alec's mum Carole, his brothers Billy and Stephen and Ireland – pictured above with a friend – his 16-year-old blonde daughter with Kim Basinger.
The reception took place in NYU's Kimmel Center.
