Kevin Federline isn’t new to the fatherhood game - he had two children with actress Shar Jackson and two more with singer Britney Spears before even meeting current wife Victoria Prince.

But on Sunday the 36-year-old reality star was beaming like a new dad as he accompanied his Mrs and their two youngest children Jordan Kay and Peyton Marie on a shopping trip in Calabasas.

The former dancer was seen carrying a bag from Toys R Us and what looked to be a new car seat.

The former model looked slim and fit wearing his usual Raiders baseball hat and baggy shorts.

A light purple button-down shirt and white high-top sneakers created a casual but dad appropriate ensemble.

Victoria, a former volleyball player and now special education teacher, glowed as she wore her long blonde hair down and wavy. Her light purple tank top, black slacks and black flip flops spelled casual summer afternoon.

Victoria carried the couple’s youngest daughter Peyton, who was born in April.

Kevin, on the other hand, carried their oldest daughter Jordan, who will turn aged three on August 15.

The little girl looked cute in sneakers and a low pony tail.

The family shopped at Toys R Us, which is across the street from the Calabasas Commons, a favorite shopping spot of the Kardashians.

With a giant shopping bag in one hand and a car seat in the other, K-Fed clearly has his daddy duties down to a science.

The day before they had reportedly watched Kevin's sons with Spears - Sean, aged eight, and Jayden, aged seven - play basketball.

The couple, who started dating in 2008, has settled into both married life and family life nicely.

The lovebirds are celebrating their one year wedding anniversary this week, on Sunday.

Last summer Kevin married his long-time girlfriend at the Hard Rock Hotel & Casino in Las Vegas in a very intimate ceremony.

Kevin was previously married to Spears, but the couple divorced in 2007.

In his wedding to Victoria, his oldest daughter with the beauty was the flower girl. He had proposed just days before.

'Victoria Prince, will you marry me in two days, in front of 30 of our closest family and friends?' Kevin asked. Victoria said yes, and told E! News all about her 'fairytale' wedding after they officially tied the knot.

'For the first time in my life, I got a taste of heaven,' Victoria said.

As far as their new daughter Peyton, Federline said after her birth, 'Words cannot express the joy my children bring me.'

Kevin's children with 37-year-old Shar are 12-year-old Kori and 10-year-old Kaleb.
