Feeling all bright: Heidi Klum puts on a brave face in a pink maxi dress, just a day after filing for divorce from Seal

She officially filed for divorce from her husband Seal yesterday after three months of separation.

But Heidi Klum cut a relaxed and smiling figure as she stepped out in Los Angeles today.

The 38-year-old German born model put on a brave face as she escorted sons Henry and Johan to their karate class in Brentwood.

However, she did cover her eyes with a pair of oversized aviator sunglasses.

The Project Runway host looked stunning in a bright pink maxi dress which she teamed with a black leather jacket and black pumps.

Her sons Henry, six, and five-year-old Johan both wore matching black T-shirts and white trousers for their class.

She was today without daughters Leni, seven, and two-year-old Lou.

Meanwhile, her estranged husband Seal looked equally chilled out as he arrived back in Los Angeles last night.

He smiled as he strolled through the LAX terminal, wearing a loose grey zip up top and sunglasses.

Yesterday saw Heidi officially file for divorce from the 49-year-old British-born singer.

Heidi cites 'irreconcilable differences' in her divorce petition, filed in L.A. County Superior Court, according to TMZ.

According to the documents filed by Heidi's lawyer, Laura Wasser, the couple signed a post-nuptial agreement.

This means they made an agreement after they got married to keep their assets completely separate.

So there is also no community property to be divided, according to sources.

Heidi is asking for joint legal custody of their four children, but she wants primary physical custody.

Heidi is also asking the judge to restore her maiden name to Klum, although she has always used it professionally.

Heidi, who is the wealthier of the pair,
is asking the judge to reject any claim for spousal support from Seal,
and not making such demands herself.

And she also makes it clear that she wants Seal to pay his own lawyer's fees.

The German supermodel parted ways from the Kiss From A Rose singer after almost seven years of marriage.

Following the split, Seal admitted he
was keen to continue to wear his wedding ring as a 'token' of how he
feels about Heidi and he had 'no intention' of removing the band anytime
soon.

He recently said: 'I think it's just
pretty much a token of how I feel about this woman. We have eight years.
Eight wonderful years together.

'Just because we have decided to
separate doesn't necessarily mean you take off your ring and you're no
longer connected to that person.

'Will we wear the ring for the rest
of our lives Who knows But right now it feels really comfortable on my
hand so I have intentions of taking it off anytime soon.'
