Jenson Button and fiancée Brittny Ward are seen for the first time since the birth of their daughter

They welcomed their second child, a baby girl they named Lenny Monrow, late last month.

And Jenson Button looked like he was settling into life as a father-of-two as the family headed out for a stroll in Beverly Hills on Wednesday.

The Formula One driver, 40, and his fiancée Brittny Ward, 30, were seen for the first time since Lenny’s arrival as they stepped out with their newborn daughter and their son Hendrix, 17 months.

Jenson also posted a sweet message writing: ‘Welcome Lenny Monrow Button. Mummy & Daddy are besotted already. Lenny has the cutest little dimples like her big brother Hendrix.  Britt is doing amazing and recovering well.’

Brittny’s 307,000 Instagram followers were quick to share their well-wishes with the couple.  

The Instagram sensation announced her second pregnancy with beau Jenson in June, with a snap of Brittny cradling her blossoming bump.

The news came just weeks after Jenson and Brittny were forced to postpone their wedding for the second time due to the COVID-19 pandemic, having pushed it back once after unexpectedly falling pregnant with their first child Hendrix. 

In the post, the ex-Playboy model looked radiant in an ethereal white dress as she cradled her blossoming bump.

The couple are already proud parents to son Hendrix, whose surprise arrival caused them to postpone their wedding. 

In May, Brittny took to Instagram to reveal their wedding will now take place in the summer of 2021.

Sharing a picture of herself with her love, she wrote: ‘I cannot wait to marry this guy… finally!

The couple had first been due to tie the knot on July 6, 2019 but Brittny fell pregnant.

She said: ‘Jenson was away when I found out, and I wanted to tell him face-to face so I waited until he returned home.

‘It was so hard to not say anything on the phone but I thought it was more special to do it in person. I gave him a little gift box with the test in it and he started crying.

‘It was a very sweet moment. It was exactly what you would want the father of your future child to do.’ 

Jenson was previously engaged to model Louise Griffiths, 40, before the couple split in 2005 after five years of dating.

The sporting legend was also married to model Jessica Michibata, but split in December 2015 after one year of marriage and a seven year romance.
