New parents Sienna Miller, 44, and Oli Green, 29, packed on the PDA as they enjoyed a child-free day for day six of Wimbledon.
The engaged couple, who welcomed a child earlier this year but have not disclosed their name or gender, shared a kiss in the stands of Centre Court at the All England Lawn Tennis Club.
Amid the UK’s third scorching heatwave of the year, which is set to bring 34C heat, Sienna kept cool in linen.
The American Sniper star looked effortlessly stylish in a taupe three-piece suit that she paired with heeled white sandals and sunglasses.
She was seen chatting to Stephen Graham as they watched a match unfold.
Also braving the heatwave was Poppy Delevingne, who looked stylish in a strapless white top paired with black palazzo pants.
The fashionistas were in good company at the tournament, as the likes of Anna Wintour, Michaela Coel and Simone Ashley were also on the grounds.

Sienna and Oli were no doubt pleased for a rare day of adult company after announcing in May that they had welcomed their second child together.
The pair are also parents to a daughter, two, whose name they have not revealed.
Sienna is now a mother of three, sharing daughter, Marlowe, 13, with ex-partner Tom Sturridge.
She announced her third pregnancy by revealing her blossoming bump at the star-studded Fashion Awards in December.
In May, she said that she’s surviving on ‘very little sleep’ as she opened up on returning to work just three weeks after giving birth while appearing on The Tonight Show With Jimmy Fallon.
During her appearance on the show she spoke about the transition of having another child and her nightmare flight over to the US to promote new action movie Jack Ryan: Ghost War.
Sienna said: ‘It feels like stringing sentences together is a bit challenging. I’m on very little sleep but I’m madly in love with my baby.
‘It’s crazy to be talking words and wearing a dress. What has happened from pajama gate.’

Asked by the host which of her children are tougher to look after, she said: ‘I would have said the teenage girl would be harder to juggle until the transatlantic flight I took yesterday with the toddler and the newborn.
‘The toddler now wins hands down. It was an absolute disaster. There’s no negotiating. I got to the immigration line and just broke down.’
Last month, Sienna’s sister Savannah confirmed the actress is engaged to Oli.
In an interview with Hello!, fashion designer Savannah praised 29-year-old Oli’s beautiful proposal.
Savannah said: ‘We are all so over the moon. It’s the happiest news, and it was beautiful, the whole thing. I can’t express how happy I am for her.’
Rumours of Sienna’s engagement began the week before when she stepped out with a new diamond ring on her wedding finger.
She showed off her eye-catching jewel on a trip to Barcelona, where she was seen leaving a party only a week after giving birth.

It is the fourth time Sienna has become a fiancée, although she has never yet been married.
Friends of the couple say former model Oli has long made known his desire to marry Sienna, despite being 15 years her junior.
One said: ‘Oli and Sienna are so ridiculously in love, they’ve got a lovely family and have such a giggle together.
‘He knows what a catch Sienna is and wants to make her his wife. Hopefully it will be fourth time lucky and Sienna will make it to the aisle this time.’
