They are in the throes of a new romance, having sparked up their relationship in the summer.

And Tobey Maguire and new girlfriend Tatiana Dieteman put on a cosy display as they stepped out for breakfast in Los Angeles on Monday.

The Spider-man actor, 43, and his model girlfriend, 26, were the picture of romance as they sweetly held hands while enjoying a caffeine fix in the sunshine.

The Tropic Thunder star kept it casual for the outing, clad in a black sweater and slate grey joggers, paired with grey and white trainers.

His chestnut locks were styled in a side-parting and he sported a neatly-trimmed beard.

Tatiana matched her beau's relaxed vibe as she rocked a black vest-top paired with lavender and white joggers.

Wrapping up, she donned a quilted black jacket and finished the look with white trainers.

Showing they were at ease with one another, Tatiana cheekily grabbed her hunky boyfriend's behind as the pair walked along.

Her caramel tresses were styled in loose waves while her pretty features were enhanced with a radiant dusting of make-up.

The pair had been rumored to be dating for some time before they were first spotted together at Leonardo DiCaprio's beach party in late August.

In 2016, Tobey split from wife Jennifer Meyer and their divorce was finalized in 2017.

The two share two children - daughter Ruby, 11, and son Otis, nine.

The exes have managed to weather the end of their marriage and still remain good friends as they co-parent their kids.

Maguire has stepped away from the spotlight of sorts. He has had just one live-action role -- 2014's Pawn Sacrifice -- over the last five years.

During that time he had been focused on producing, which includes the upcoming biopic The Best of Enemies, starring Sam Rockwell and Taraji P. Henson.

The California native gained worldwide recognition for his role as Peter Parker/Spider-Man in Sam Raimi's Spider-Man trilogy that began in 2002.

His stellar Hollywood resume also includes such films as Pleasantville (1998), The Cider House Rules (1999), The Wonder Boys (2000), The Good German (2006), Brothers (2009) and The Great Gatsby (2013).
