In a move that is bound to spark further talk about a hot new romance, the pair gazed over a cell phone during the two hour trip on the high-speed railway service between the two cities.
Baptiste, 22, and the 27-year-old pop beauty — sporting bright blue hair and transparent lace top — were “very, very cute together,” an onlooker told Celebuzz, exclusively.
Katy looked smitten as she smiled and touched hands with the muscular model, who has been the face of Chanel since 2008, when Karl Lagerfeld proclaimed him as his muse.
The pair also whispered to each other and chatted with friends who were travelling as part of their entourage.
“They very much looked like a couple,” the onlooker told Celebuzz.
The dinner date came 14 months after Baptiste admitted in an interview: “If I could make her (Katy) divorce her husband, I’d marry her.”
In December, Katy’s husband of 14 months Russell Brand filed for divorce in a Los Angeles court, citing “irreconcilable differences.”
She recently wrapped a 124-show world tour in support of her third studio album, “Teenage Dream.”
