But perhaps Lachey was also thinking about Derek Jeter.
Why would the soulful crooner have the Yankees shortstop on his mind? Because Jeter has had Nick's girlfriend, Vanessa Minnillo, on a lot more than just his mind in the past; the pair used to date.
Now, however, maybe Lachey can relax about it. Rumors are swirling that Jeter has moved on from Vanessa to another hottie: Jessica Biel.
The Yankees captain and The Illusionist star were spotted at Hollywood hot spot, Hyde, Tuesday night. They were "laughing and giggling together," according to Page Six, while others sources state Jeter actually massaged Biel's shoulders.
That's like almost first base.
The baseball star has also dated Mariah Carey in the past. He's really good looking.
