Private: 'Everyone knows they are dating, but they still want to keep it private'

'Katie and Jamie are still careful about being photographed together,' a source told People.

'Everyone knows they are dating, but they still want to keep it private.'

So private that the two are often apart for long periods of time.

'It’s not uncommon for them to go long stretches without seeing each other,' a source dished to ET in June.

Love: 'They’re still very, very private. You’re not going to hear or see every time they’re together because they don’t flaunt their relationship in public,' a source told ET

'And they’re still very, very private. You’re not going to hear or see every time they’re together because they don’t flaunt their relationship in public.'

The only time they have been seen packing on the PDA was during a romantic beach date in Malibu in 2017.

The duo reportedly got together one year following Katie's divorce from Tom Cruise, back in 2013.

She married the famous Scientologist in 2006 and divorced in 2012. Since then the pair have not been seen together.

The former power couple have one child together, 12-year-old Suri, who the Jerry Maguire actor has not been photographed with in public for four years.
