Actress Scarlett Johansson and her boyfriend Colin Jost have "a great energy between them".
Johansson, 32, started dating the "Saturday Night Live" star earlier this year and was spotted cheering for him in the crowd at Jost's comedy show in Boston on October 28, reports.
"Scarlett was very supportive of Colin. She sat fourth row and was laughing hysterically along with the rest of the audience," a source said.
"They seemed very much like a new couple, holding hands and had a great energy in between them," the source added.
