Jennifer Garner and her boyfriend John Miller were the ultimate cute couple on Sunday morning.

Miller gave his girlfriend a sweet smooch as he supported her at a running event she was hosting benefitting Save The Children.

Garner, 53, flung her arms around her love, greeted him with a kiss, and held him close.

For over two months, the Alias actress has diligently run a mile each day to support raising funds for hungry children, with Sunday’s event being the grand finale of all her efforts.

She invited fans to join her at the event in a recent Instagram post that chronicled her daily jogs. 

‘Join me on June 22nd to run a mile for @savethechildren! I’ve been running a mile daily for the past 67 days— just $67 can help save a child from the threat of starvation,’ the Save The Children ambassador stated. ‘Now I’m inviting you to be part of my final mile on Sunday, June 22nd with @becsgentry and @brooksrunning in support of Save the Children— whether in LA or from wherever you are! Let’s celebrate what we’ve achieved and continue this movement with strength.’

And John was there rooting his girlfriend on as she concluded her running streak.

John arrived in a casual olive green T-shirt, jeans, and a cup of coffee to get the day going.

As for Jennifer, she wore a ’67 Strong 4 Kids’ T-shirt, leggings, and her hair styled into braided pigtails.  

The 13 Going On 30 actress has been dating Miller on-off since 2018 and recently it’s been reported that they have begun living together part-time.

In a recent update of Garner and Miller’s relationship, Us Weekly reported that John is now living with the Alias actress ‘part time.’

‘John is basically living with Jennifer,’ a source told the publication back in April, noting it was only ‘part time.’

The report also mentioned that he vacated his Los Angeles residence after wildfires hit numerous areas in the Southern California city, and he is still searching for a new home.

‘He has an office in L.A. and splits his time between staying there and at Jennifer’s home,’ the source said.

‘But he’s been staying with Jennifer more often [and] doesn’t want to impose, so he’s looking for his own place… [and] deciding whether he’ll rent or buy.’

Jennifer and John have been dating since 2018.

Garner is also close to her ex-husband Ben Affleck whom she has her kids with: Violet, 19, Seraphina, 16, and Samuel, 13.

Ben bought a house just minutes from Garner so he can be closer to his kids. 

In March, DailyMail.com learned Jennifer and John went on a cuddly date together.

The lovebirds were ‘holding hands and kissing’ and acting ‘very cute with one another’ when walking through the Brentwood Country Mart in Los Angeles.

The PDA session took place in March in the evening, said the eyewitness.

‘Both were dressed casually and she had no makeup on, her hair down. He had on a coat and jeans.’

The source added that there was plenty of affection between the two of them. ‘They held hands and kissed and looked like a very normal couple with no Hollywood weirdness.’
