The couple were snapped at the Polo Lounge at the Beverly Hills Hotel, where they enjoyed a meal before heading to Jennifer's Hollywood Hills pad.
'They spent the day together at Jen's place,' a source tells People. 'They were happy to see each other.'
Jennifer also took 30-year-old John to see best pals Courteney Cox, 43, and husband David Arquette, 36, at their home in Malibu on Sunday.
They spent the evening together watching the sunset.
