Just good jeans! Heidi Klum shows off her natural beauty in casual double denim outfit as she arrives at LAX

She's often seen dressed to the nines, but Heidi Klum picked a low-key outfit as she arrived at Los Angeles International Airport on Monday.

The 42-year-old went for a retro look in a denim shirt, which was unbuttoned over a black T-shirt, tucked into skinny jeans.

Heidi had a thin tan-coloured belt around her tiny waist and kept warm on an uncharacteristically chilly LA day with a plaid blue wool coat.

The supermodel pulled her blonde locks into a fuss-free messy bun and sported natural make-up under her aviator sunglasses. 

Heidi couldn't resist adding a touch of glamour however in a pair of teal suede pumps with high heels. 

The jet setting star had shared a selfie which showed her pretending to sleep while on a flight three days earlier. 

Before she left Los Angeles, Heidi celebrated Easter early with her four children, sharing a photo which showed them all wearing bunny ears.

The German beauty has sons Henry, 10, and Johan, nine, and six-year-old daughter Lou from her marriage to Seal, as well as 11-year-old daughter Leni from a previous relationship with Flavio Briatore.

However Heidi has said explicitly that 'Seal is Leni's father', and the singer officially adopted her in 2009. The couple split in January 2012 after almost seven years of marriage.

The stars have each moved on since, with Heidi in a relationship with Vito Schnabel and Seal dating Erica Packer.

Heidi visited London earlier this month, where she made an appearance on Lorraine and admitted that she still finds it 'intimidating' to be in a bikini.

'Wearing a bikini is always hard because you're in public, so it's always intimidating a little bit,' she confessed on the ITV show.

Heidi added: 'You know with lingerie it's different, it's something more for yourself. But being on the beach "almost naked" it's a little intimidating for me too at times.'

The Project Runway host also revealed her tips for any aspiring models out there. 

'Always stay true to yourself,' she advised. 'You've gotta look into the mirror and being happy with what you see at the end of the day.'

Heidi, who got her start at the age of 18 after beating 25,00 hopefuls in a national modelling competition, added: 'Especially in the beginning because people don't care about your feelings.'
