Selena Gomez is the definition of cute, and her recently-leaked Christmas card is an adorable shot of her with her very festive puppy Baylor!

Selena, 19, made the adorable cards for a promotion with Postcard On The Run, and fans who signed up received them. The message inside reads, “Hey All! You made my holiday season bright. If you didn’t see the YouTube video, I did some decorating myself with your postcards :) Happy Holidays!! Lots of love, Selena.” She also signed her name as ‘Sel’ — she’s the best!

Do YOU think these are the best Christmas cards of the season, HollywoodLifers?

We’ve been obsessed with Selena Gomez‘s dog Baylor ever since she first tweeted a picture of him to her fans, but we learned something we never knew about the puppy when Selena sat down for an interview with Kiss FM. “It wasn’t meant to be for me,” Selena confessed. “I was going to give it to my nana as a gift, but I ended up falling in love with him, so I had to keep him.”

Now that she’s fallen in love with him, Selena says she can’t stand to be away from Baylor.

“I miss him,” she said. “I wish he could come with us everywhere. But he’s growing every week, so he’s at home with my mama. … He’s been my sweetheart, my cuddle bunny.”

And not only is Baylor doing well after his surgery — he was recently hospitalized for eating rocks — but he’s also learning some new tricks!

“We taught him how to sit and give paw,” Selena said. “We got him when he was a puppy, so he was very easy to teach. But the rest was my stepdad — he’s so good with dogs.”

Justin will be performing in NYC’s Times Square on New Year’s Eve but don’t expect him to be smooching any Beliebers — is it to spare Selena Gomez’s feelings?

Justin Bieber is a one woman kind of guy! The 17-year-old popstar reveals in a new interview seen here on video, that although he’s performing on New Year’s Eve with Lady Gaga - when the clock strikes midnight, he won’t be planting a wet one on her!

Even though Justin is told that kissing Lady Gaga would be good luck, Justin responds: “I don’t think my girlfriend Selena would like that too much.”

UPDATE – Lawsuit: Mariah Yeater Claims She Has Justin Bieber’s Baby. Who is she? Here are the Mariah Yeater photos.

Isn’t Selena just the luckiest girl in the world? Justin is totally devoted to her! But Selena is just as in love with our Biebs! Selena landed in LA on Oct. 31 and we bet she’s going to see Justin perform tonight on Dancing with the Stars!

Poor Selena Gomez has been under the weather this week, but she’s been such a trooper — she hasn’t cancelled one performance! Maybe it’s because she has her new puppy, Baylor, to keep her company…

The 19-year-old performer took Baylor, a 10-week-old husky-mix rescue, out for a walk outside her hotel in Toronto, Canada Oct. 25 and seemed to be feeling much better than she did the previous day.

Selena adopted Baylor with her boyfriend, Justin Bieber, last week when they were in Winnipeg together. With Justin away, Baylor is the one keeping his mom company!
