It looks like the Seewald family is becoming just as popular as the Duggars these days. Jessa Duggar has posted a new video of her sister-in-law Danielle on her Instagram account after many of her fans were wowed by the teenager's amazing voice on a recent episode of 19 Kids & Counting.

Ladies and gentleman: "Immanuel" by Ms. Danielle Seewald (14 yrs. old). Listen to the entire song on my Facebook page-- www.facebook.com/JessaSeewald."

Meanwhile, there have been rumors that Duggar might be expecting her first child, despite the fact that she's only been married for a little over one month.

Although Duggar herself hasn't said anything about the speculation, an insider tells Radar Online on Monday that she "wouldn't be surprised" if the new bride already had a bun in her oven.

The source told the site, "The couple views sex as a 'present' from God and they weren't afraid to open it on their wedding day. I wouldn't be surprised if Jessa was pregnant already."

The source added that there is a good chance that Duggar will be pregnant soon enough if she isn't already as their family doesn't believe in birth control, adding that she "would be the perfect mother."
