It's a sad day for single ladies around the world, as Closer Weekly reported earlier today that Fuller House star John Stamos, 54, is engaged to his girlfriend, Caitlin McHugh, 31, after nearly two years of dating. However, will their 23-year age gap ultimately get the best of them? We spoke with a bunch of relationship and body language experts, who have revealed whether or not they think they could last forever.

"Let's consider the facts: John Stamos is the antithesis of an old man. He's hot, handsome, and successful. And contrary to the Playboy image that's projected onto him by others, John's a 'relationship guy' at heart," says NYC-based relationship expert Susan Winter.

"Caitlin and John have been dating for a year and a half. This is not a fly-by-night romance," she continued. "This is a long enough time period to see how their dispositions (and lifestyles) meld. They've gone through their initial honeymoon period, and have had time to find themselves confronted with disagreements as well as resolutions."

While their relationship has potential, body language expert Patti Wood, who is also an Allergan partner on the Eyepowerment Campaign, shares she believes there might be tension in their relationship. After observing the photo above, Patti shares, "The great thing about that photo is that he has the full front of his body at what I call the heart window. It's called the ventral front, that's the belly area, and the pelvis — all those areas he has touching her, which is incredibly intimate and shows that they have a sexual relationship."

However, after seeing a second photo, Patti continues with, "His [left] hand [is placed] in an unusual position. The tips of the fingers are tightly curled in and away from her — that's unusual and shows a lot of tension. It emphasizes or highlights that there's a little bit of tension about being fully connected. That other part of that is his legs are crossed away from her, and that's an indication that he wants to be seen as his own person and not as a unit with her."
