Jennifer Aniston had a cute encounter with Jon Hamm this week.

The 53-year-old Friends vet was seen chatting up her 51-year-old Morning Show costar Jon Hamm as she plugged Vital Proteins protein bars in a video shared to Instagram on Wednesday. The beauty let her cardigan fall off her tanned shoulders to show off her tank top as she looked up at him. 

The two have been romantically linked by tabloids such as Star, even though he has gushed about how much he is in love and wants to settle down with his current girlfriend, Anna Osceola.

In September Hamm said he was 'very much' in love with Osceola.

His relationship is 'even more meaningful' he said adding he is open to 'the possibility of things like being married, having kids, you know, defining a new version of happiness, life, wellness.'

He told Howard Stern on his SiriusXM show, 'All that stuff that sounds hokey and whatever but it's real and, for want of a better word, it's what I'm working for.

What else is there other than that.'

Meanwhile, Aniston told Allure magazine this fall she wants to date and is open to love after two divorces.

In the new video posted to Aniston's Instagram page she is seen offering Vital Proteins power bars - which are 160 calories - to the Morning Show crew. Several people snap them up and she is left with none.

That is when Hamm shows up, coming behind her stand.

He notes the bars are gone, and that is when she offers him a protein packet to put in his coffee.

He asks if it is free, she says yes, and he takes off with the packet, which leaves her ready for an eye roll.

'This is a Vital Proteins bar that I helped create. It's very exciting. It's made with all these delicious ingredients,' she said.

Then she takes a bite out of one of them: 'Ohhh it's just so good, it's so good.'

The beauty had a fresh tan and nice highlights from her hairstylist pal Chris McMillan.

She held up the bar which had a beige cover with white writing on it. It said Vital Proteins and Jennifer Aniston just below it.  

There are three flavors: Peanut Butter Fudge - Maca & Maqui Berry, Cold Brew Coffee - Maca & Cordyceps, and Dark Chocolate Coconut - Reishi & Lion's Mane.

On the Vital Proteins website it reads: 'Three delicious protein and collagen bars developed in collaboration with our Chief Creative Officer, Jennifer Aniston.

 

'Perfect for any time of day: morning, between meals, or on the go. 

'A satisfying bar in a convenient, stash-and-go size for a "whenever" snack — under 200 calories!'

According to the site, 'Collagen is the body's most abundant protein and helps give structure to our hair, skin, nails, bones, ligaments and tendons. Thanks to collagen, we're better able to move, bend and stretch.

Collagen is also behind helping hair shine, skin glow and nails stay strong.'

Collagen is a protein made up of amino acids glycine, proline, hydroxyproline and arginine.

In April the star, who is a size 2, shared with First For Women magazine exactly how she is able to look so youthful even when she works full time on her acting career and heads up companies like LolaVie Haircare.

The 5ft5in cover girl admitted that she keeps her diet in check by starting her day off with warm lemon water and she also takes climbing classes on her stair climber.

But the best part of her day is the time she sets aside to meditate, said the looker.

A stunner:  Aniston has been able to maintain her incredible size 2 shape even as she settled into her 50s. Seen in the film Just Go With It...

The Cake actress added: 'When I wake up I have warm lemon water, then a shake or avocado and eggs.

I found ways to make eggs every which way.'

The ex-wife of Oscar-winning actor Brad Pitt then shared: 'But I also do oatmeal with an egg white whipped in.

'Do it right before the oatmeal is finished cooking - it gives extra protein and this fluffy texture that's delicious.'

In an interview with Radio Times promoting her Apple TV+ show The Morning Show, Aniston revealed that intermittent fasting (IF) has changed her life.

She practices a version of IF called the 16:8 diet.

'I do intermittent fasting, so no food in the morning I noticed a big difference in going without solid food for 16 hours.' 

As far as working out, she told First For Women puts in the work but likes variety.
