No first day of work jitters here!
The New Kids On The Block crooner joined his leading lady up on the famous sofa, coming out with flowers and hugging all of the women on the panel. He even planted a special smooch for his leading lady.
And while he was actually on hand to promote his latest endeavor, the television show Blue Bloods, it certainly didn't hurt that he could support his gal pal while doing so.
Two birds, one stone!

It seems that McCarthy, despite having oodles of TV experience, was a ball of nerves before stepping out onto The View's set.
Just yesterday, she tweeted, "Thx for all my good luck comments about 2morrow I'm nervous & excited."
And she wasn't the only one who was stepping out of her comfort zone for the show.
Wahlberg addressed his NKOTB fans, who are known as Blockheads, and explained how unusual it is for him to be so public about his personal life.
"To all my BH's, I may be a bit of an extrovert (no way… really?), but I'm also very private. Your support meant a lot today."
The two made their first red carpet appearance together in August at a Dancing With the Stars charity event at the Hotel Baker in St. Charles, Ill.
They reportedly started dating earlier this summer, after Wahlberg appeared on her talk show, The Jenny McCarthy Show in March, according to Us Weekly.
Did you watch today's show? What did you think of McCarthy's first day on the job?!
