Starting off Monday at E3's PlayStation Lounge in L.A., the couple took time out of a video game duel – Patton beat Thicke – to sing each others' praises.
"Robin glowed as he spoke about Paula, even calling her his mentor," an onlooker tells PEOPLE. "Paula seemed [surprised] by his comment and gave him a big kiss, jokingly saying that this just bought him another 10 years. They continued to gush about each other back and forth throughout the night."
The romantic outings continued on Wednesday, when the upbeat pair headed to Soho House in West Hollywood for the Sundance Institute Benefit presented by Tiffany & Co.
"They told other people at the event that they were on 'date night,' " an attendee says. "They looked visibly excited to spend time together."
The source adds that the couple was able to step out for the evening with the help of a babysitter, who looked over their son Julian Fuego.
